Question

at a state fair, attendees can win tokens that are worth a different number of points depending on the shape. one attendee won s square tokens and c circle tokens worth a total of 1,120 points. the equation 80s + 90c = 1,120 represents this situation. how many more points is a circle token worth than a square token? (a) 950 (b) 90 (c) 80 (d) 10

Explanation:

Step1: Identify point - values

A square token is worth 80 points and a circle token is worth 90 points.

Step2: Calculate the difference

Subtract the point - value of a square token from the point - value of a circle token: $90 - 80$.
$90-80 = 10$

Answer:

D. 10
