Joseph and his younger brother, Ryan, are taking a backpacking trip and must pack a total of 12 gallons of water. Ryan will carry 4 less than half the number of gallons Joseph will carry. Let x be the number of gallons Joseph carries and let y be the number of gallons Ryan carries.

y = 1/2x – 4 

x + y = 12

A customer at a garden store paid $44 for 6 packages of seeds and 4 fruit trees. At the same store, a second customer paid $8 more than the first customer for 2 packages of seeds and 6 fruit trees. Let x be the price of a package of seeds and y be the price of a fruit tree.

6x + 4y = 44 

2x + 6y = 52

A package of seeds costs $2  

A fruit tree costs $8

At Juicy Juke, Zoey orders a combination of smoothies and juices for her family. The juices cost $1 and the smoothies cost $3. Zoey ordered a total of 6 items and spent $14. Let x be the number of juices she ordered, and y be the number of smoothies she ordered.

x + y = 6 

x + 3y = 14

Zoey ordered 2 juices and 4 smoothies

A hair stylist offers clients haircuts and coloring treatments. On Monday, she did 5 haircuts and 3 color treatments and earned $340. On Wednesday, she did 2 haircuts and 6 color treatments and earned $400. Write and solve a system of equations to determine the amount the stylist earn

5h +3c = 340

2h + 6c = 400 

h = $35 and c = $55
