Question

SHOPPING For Exercises $66$ and $67$, use the following information.

Javier had $25.04$ when he went to the mall. His friend Sally had $32.67$. Javier wanted to buy a shirt for $27.89$. 

$67.$ How much money did that leave Sally?

Step-by-Step Solution

Answer

The remaining amount that Sally has is $29.82$.

Step 1 – Definition of equation.

Equation is a mathematical statement it which two expressions are equal to each other.

Step 2 – Given information.

Javier had $25.04$ and Sally had $32.67$.

The price of shirt is $27.89$.

Step 3 – Write the equation for borrowing amount and solve it.

Let $x$ be the amount Javier have to borrow from Sally to buy the shirt. Then,

$25.04+x=27.89$

Subtract $25.04$ from both sides.

$\begin{array}{l}25.04+x-25.04=27.89-25.04\\ x=2.85\end{array}$

Step 4 – Write the equation for remaining amount and solve it.

Let $y$ be the remaining amount that Sally has. Then,

$\begin{array}{l}y=32.67-2.85\\ =29.82\end{array}$

Thus, the remaining amount that Sally has is $29.82$.
