Question

at an online store, each purchase earns the same number of points (called reward points). abdul has made 5 purchases and has earned 8.5 points.
(a) let n be the number of points earned with each purchase. write an equation that can be used to find n. first choose an appropriate form. then fill in the blanks with the letter n and the numbers 5 and 8.5.
(b) solve your equation for n to find the number of points earned with each purchase.

Explanation:

Step1: Define the relationship

Let \( n \) be points per purchase. Total points = purchases × points per purchase. So \( 5n = 8.5 \).

Step2: Solve for \( n \)

Divide both sides by 5: \( n=\frac{8.5}{5} \).

Step3: Calculate the value

\( \frac{8.5}{5}=1.7 \).

Answer:

The number of points per purchase is \( 1.7 \).
