The first five months Paul paid  and in the next seven months he paid 24.

<h3>What is a Discount ?</h3>

Discounts are defined as lowered prices or the sale of an item for less than it would typically cost. The fundamental formula for calculating a discount is to multiply the original price by the given percentage rate in decimal form. We must deduct the discount from the original price to determine the item's sale price. A discount is an amount that is subtracted from the regular price of an item.

Paul represent his plan in the form of equation:

5 x+7(x+8.50)=245.50

Where x  is an amount for the first 5 months that is paid by Paul after the discount and (x+8.50)  is an amount for the next 7 month after discount.

&\Rightarrow \quad 5 x+7 x+59.50=245.50 \\&\Rightarrow \quad 12 x=186 \\&\Rightarrow \quad x=\frac{186}{12} \\&\Rightarrow \quad x=15.50\end{aligned}

For the next 7 month:

(x+8.50)=(15.50+8.50)=\$ 24

Therefore, The first 5 months Paul paid $ 15.50, and in the next 7 months he paid $ 24.
