Question

1. Calvin goes shopping over the weekend and buys a new pair of shoes, a t-shirt, a pair of

sunglasses, and a hat that costs $9. The shoes are twice as much as the shirt, and the
sunglasses are half as much as the shirt. The total cost of his purchase is $65.

a. Using the lines above, write an equation to represent his purchase using "s" for the cost of
the shirt.
b. Simplify the equation by combining like terms.
c. Solve the equation.
d. What is the cost of each item?
Shoes:
Shirt:
Sunglasses

Answer 1

A. 2s+s+1/2s+9=65
B. 3.5s+9=65
C. Subtract 9 from both sides to get: 3.5s=56 and then divide both sides by 3.5 to get s (the cost of the shirt) which is s=16
D. Shoes cost $32, shirt costs $16, and the sunglasses cost $8
