Carmen has $30 in store bucks and a 25% discount coupon for a local department store. What maximum dollar amount can Carmen purc
hram777 [196]

The maximum amount can Carmen purchase so that after her store bucks and discount are applied is \boxed{\$ 110}.

Further Explanation:

Given:

Carmen has \$ 30 in store bucks.

A 25\% discount coupon for a local department store.

The total amount should be less than \$ 60 before sales tax.

Explanation:

Consider the amount of the purchase as A.

The Carmen has \$ 30 in store bucks.

The new amount will be \left( {A - 30} \right).

There is a 25\% discount coupon for a local department store.

The amount after discount can be calculated as follows,

\begin{aligned}{\text{Amount}} &= \left( {1 - 0.25} \right) \times \left( {A - 30} \right) \\&= 0.75\left( {A - 30} \right) \\\end{alignedd}

The total amount should be less than \$ 60 before sales tax.

The maximum amount can Carmen purchases so that after her store bucks and discount are applied can be calculated as follows,

\begin{aligned}0.75\left( {A - 30} \right) &\leqslant 60 \\\frac{{0.75\left( {A - 30} \right)}}{{0.75}} &\leqslant \frac{{60}}{{0.75}} \\ A - 30 &\leqslant 80 \\A - 30 + 30 &\leqslant 80 + 30 \\A &\leqslant 110 \\\end{aligned}

The maximum amount can Carmen purchase so that after her store bucks and discount are applied is \boxed{\$ 110}.
