Question

SHOPPING Evelina is shopping for back-to-school clothes. She bought 3 skirts, 2 pairs of jeans, and 4 sweaters. Write and evaluate an expression to find out how much money Evelina spent on clothes, without including sales tax.

Step-by-Step Solution

Answer

The total amount spent is $393.

Step 1. Write down the given information.

Evelina bought 3 skirts, 2 pairs of jeans and 4 sweaters. The cost of each skirt, jeans, the sweater is $35.99,$49.99,$32.99 respectively.

Step 2. Evaluate the cost of shirt jeans and sweaters.

Let the cost of each skirt, jeans, the sweater be $a,b,c$ respectively

She bought 3 skirts so the amount she spent is $3a$.

She bought 2 pairs of jeans so the amount she spent is $2\times 2\times b=4b$

She bought 4 sweaters so the amount she spent is $4c$

Step 3. Evaluate the total amount spent.

The total amount is $T=3a+4b+4c$

Use $a=35.99,b=49.99,c=32.99$ the above equation to get

$\begin{array}{l}T=3\left(35.99\right)+4\left(49.99\right)+4\left(32.99\right)\\ T=\$393\end{array}$
