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,

where are the choices?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
