Giselle bought a dress for $35 and three t-shirts. she used a coupon for $2.50 off each t-shirt. the total cost can be modeled by the expression
35+3(n.2.5). what does n - 2.5 represent?

n - 2.5 represent the total cost on each T shirt after coupon is applied

Step-by-step explanation:.

Given parameters

Modeling of the total cost = 35 + 3(n - 2.5)

The general format of models like this is as follows;

Price + quantity (cost after coupon)

Coupon literally is a code that are used to obtain a discount on the current purchase

By comparison;

Price = 35 (i.e. current dress price).

Quantity = n (i.e. the number of shirts bought)

Lastly, cost after coupon = n - 2.5

It is stated that she applies a coupon on each T shirt

This can be interpreted to: removing a total discount of $2.50 from the three t+shirt

By removing, the expression is given as negative $2.5

Hence n - 2.5 represent the total cost on each T shirt after coupon is applied
