The first five months Paul paid and in the next seven months he paid 24.
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:
[tex]5 x+7(x+8.50)=245.50[/tex]
Where x is an amount for the first [tex]5[/tex] months that is paid by Paul after the discount and [tex](x+8.50)[/tex] is an amount for the next [tex]7[/tex] month after discount.
[tex]&\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}[/tex]
For the next 7 month:
[tex](x+8.50)=(15.50+8.50)=\$ 24[/tex]
Therefore, The first [tex]5[/tex] months Paul paid $ 15.50, and in the next [tex]7[/tex] months he paid $ 24.
