Jim and Sam each ordered an egg sandwich for breakfast. Jim also ordered coffee for $1. If the total bill was $9.50, how much did each egg sandwich cost?
$1 + 2E = $9.50
2E = $8.50
E = $4.25
6(h + -7) = 30
h = 12
-18m/6 = -12
m = 4
$54 = $21(2) + $4D
$54 = $42 + $4D
$12 = $4D

One pizza delivered from the local restaurant costs $18. Two pizzas costs $26. Three pizzas cost $34. Is the cost proportional? Why or why not?
No. The increase per pie is $8. There is a $10 tip/delivery charge that makes it not proportional.
14.8 = 7.9 + z
6.9 = z

The quotient between a number x and 15 is 5. Write the equation and solve it.
x/15 = 5 [x = 75]
-15 = 5(n + 3)
0 = n
-3/4x + 4 (4 - 2) = -16
x = 32
It costs $25 for a car to enter the park. It costs an additional $3 for every person in the car to use the park's facilities. How much would it cost for a family of 7 arriving in 1 car to use the park for the day?
