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

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

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,

x=25tan30=14.43 or the answer is b
