The total cost of items Gina bought on her shopping trip given the percentage discount is $26.31
Given:
<em>cost of two books</em> = $4.99 + $12.99
= $17.98
<em>Amount paid for books</em> = $17.98 - 10% of $17.98
= 17.98 - 0.1 × 17.98
= 17.98 - 1.798
= $16.182
<em>Cost of notebooks = quantity × price</em>
= 2 × $2.88
= $5.76
<em>cost of composition books = quantity × price</em>
= 3 × $0.79
= $2.37
<em>cost of pencil packs</em> = quantity × price
= 2 × $1.89
= $3.78
Total cost = $5.76 + $2.37 + $3.78
= $11.91
<em>Amount paid for school supplies </em>= $11.91 - 15% of $11.91
= 11.91 - 0.15 × 11.91
= 11.91 - 1.7865
= $10.1235
Therefore,
total cost of all items Gina bought = $16.182 + $10.1235
= $26.3055
Approximately, $26.31
