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

good luck!

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
