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

How do you get domain and range
Lunna [17]

Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
