Question

Sam wants to paint his living room and he needs to buy some materials. Cans of paint cost $10 each and paint brushes each cost $2 each. If Sam plans to spend exactly $50 on painting materials, which of the following equations represents the number of cans of paint (c) and the number of paint brushes (b) that he can purchase?

A. $10c + $2b = $50
B. $10b + $2c = $50
C. $12(c + b) = $50
D. $2(5c × b) = $50

Answer 1

A)

Because they are buying cans that cost $10 but we don’t know how much cans so 10c ($10 x amount of cans) and same goes for the $2 brushes ($2 x amount of brushes). Which will then end up the amount of all

Answer 2

10 is the value of every can and $ 2 is the cost of every brush, then the total cost is equal 50, an it is

$10 c + $ 2 b = 50, this is the equation that represents the total cost,
