Given:

Tim buys 4 gallons of white paint and 3 gallons of blue paint.

The cost of the each gallons of white paint is $\ 15.72$ and the cost of each gallons of blue paint is $\ 21.87$.

Calculation:

Let $x$ be the cost of the 4 gallons of white paint and $y$ be the cost of the blue paint.

The cost of each gallons of white paint is $\ 15.72$.

Therefore, the cost of the 4 gallons of white paint can be calculated as follows,

$\begin{aligned}x&=4\times\ 15.72\\&=\ 62.88\\\end{aligned}$

The cost of each gallons of blue paint is $\bf\ 21.87$.

The cost of the 3 gallons of blue paint can be calculated as follows,

$\begin{aligned}y&=3\times\ 21.87\\&=\ 65.61\\\end{aligned}$

The total money that is spend for all the paint is $\boxed{x+y}$.

The total spend money can be calculated as,

$\begin{aligned}x+y&=\ 62.88+\ 65.61\\&=\ 128.49\\\end{aligned}$

Answer 2

$128.49

Further explanation

Given:

• Tim is painting his storage shed.
• He buys 4 gallons of white paint and 3 gallons of blue paint.
• Each gallon of white paint costs $15.72.
• Each gallon of blue pain costs $21.87.

Question:

How much will Tim spend on the paint?

The Process:

We first calculate the total cost spent on each color of the paint.

Total costs of white paint  $\boxed{ \ = 4 \ gallons \times \frac{ \ 15.72}{1 \ gallon} = \boxed{ \ \ 62.88 \ } \ }$

Total costs of blue paint  $\boxed{ \ = 3 \ gallons \times \frac{ \ 21.87}{1 \ gallon} = \boxed{ \ \ 65.61 \ } \ }$

The overall cost of painting is $\boxed{ \ \ 62.88 + \ 65.61 = \boxed{ \ \ 128.49 \ } \ }$

Quick Steps:

Total costs  $\boxed{ \ = \bigg(4 \ gallons \times \frac{ \ 15.72}{1 \ gallon} \bigg) + \bigg(3 \ gallons \times \frac{ \ 21.87}{1 \ gallon} \bigg) \ }$

$\boxed{ \ \ 62.88 + \ 65.61 = \boxed{ \ \ 128.49 \ } \ }$

Therefore, Tim will spend the total costs to paint his storage shed as much $128.49.
