A truck driver travels at an average speed of 53 miles per hour. Which equation can be used to find d, the distance the truck driver will travel in 3.5 hours? a) d= 53 x 3.5 b) d= 3.5/53 c) d= 53/3.5 d) d= 3.5 + 53
a) d= 53 x 3.5 because distance = rate x time (d=rt)

April pays $33 for 22 feet of fabric. If the price per foot is the same, how much will April have to pay in order to buy 15 feet of fabric? a) $22.50 b) $48.40 c) $10.00 d) $25.00
What is a) $22.50 Set it up as a proportion money to Feet, then cross multiply & divide to solve for X. 33 x 15= 495, 495/22= 22.50

Jodie wants to buy a shirt regularly priced at $20. The shirt is on sale for 15% off the regurlar price. Which equation can be used to determine, s, the sale price of the shirt, not including tax? a) s= 20 - (20)(0.15) b) s= 20 - (20+ 0.15) c) s= 20(0.15) d) s= 20 + 0.15
a) s= 20 - (20)(0.15) because you must first find the amount of the discount and then subtract it from the original amount in order to determine the sale price of the shirt, not including tax.

Mary earns a salary of $200 per week plus an additional 5% commission on her sales. If Mary's salary increases by $25 and her commission increases to 6%, how much will she earn if her weekly sales are $2,500? a) $325.00 b) $375.00 c) $525.00 d) $700.00
What is b) $375.00 Set up as proportion (commision to Total Sales) then cross multiply and divide to find X. Finally, add commision to salary to get total.

A recipe for 12 waffles calls for 1 1/2 cups of milk, 2 1/4 cups of flour, and 1 1/3 cups of other ingredients. How many cups of milk, flour, and other ingredients are needed to make 36 waffles?
What is 15 1/4 cups 12 waffles = 1.5 +2.25 +1.33 12 waffles = 5.08 total cups so, 12 x ? = 36 waffles 12(3)= 36 waffles therefore, 5.08(3) = 15.24 or approximately 15 1/4 cups

Carl bought 3 table lamps for $129.90. If each lamp cost $40.00 before tax was added, what tax rate did she pay on the 3 lamps? a) 7.5% b) 43.3% c) 30.70% d) 8.25%
What is 8.25% Each lamp = $40 x 3 lamps = 120 before taxes. so 129.90 - 120.00= 9.90 (tax paid). then use proportions to find correct tax rate.

Michael decorated his brother's bedroom walls with outlines of regular hexagons. He used a sample regular hexagon on paper with sides of 8cm, projected a scaled up image of the hexagon on the walls, and then traced that image with paint. If the projector dilated the hexagon image by a factor of 2.4, then what is the length of each side of the hexagons painted on his brother's walls?
What is 19.2 cm

To cover his bulletin bard, coach Pence needs 1 1/2 yards of fabric and 6 1/4 yards of trim. If the fabric costs $2.79 per yard and the trim costs $1.19 per yard, which equation can be used to find, c, the total cost of covering the bulletin board? a) c= (2.79 + 1.5) + (1.19 +6.25) b) c= (2.79 x 1.5) + (1.19 x 6.25) c) c= (2.79 + 1.5) - (1.19 + 6.25) d) c= (2.79 x 1.5) - (1.19 x 6.25)
b) c= (2.79 x 1.5) + (1.19 x 6.25)
