Leon bought pairs of socks that cost per pair, shirts that cost each, and a dozen pencils that cost for . How much did Leon spend in total?

Explanation

First, let's find the cost of the socks Leon bought.

$\text{Socks} = $3.12\times5=$16.05$

Then find the total cost of the shirts Leon bought.

$\text{Shirts}=9.89\times2=$19.78$

Next, find the cost of the pencils. Watch out here because the pencils are priced per 6. There are two 6's in a dozen.

$\text{ Pencil} =\frac{12}{6} \times0.45= $0.90$

Add these subtotals together to get the answer.
