Question

Jessica and Nancy are members of different video game libraries. Jessica pays a membership fee of $40, and she pays $5 for every video game she rents. The following function shows the total amount of money, y, in dollars, that Nancy pays for renting x number of video games: y = 4x + 30.
How many more dollars does Jessica pay for a membership fee than Nancy?

Answer 1

The two equations are
y=5x +40
y=4x+30
Jessica pay $40; Nancy $30
So Jessica pays $10 more in membership

Answer 2

The answer is 10 more dollars
(Y)=4(5)+30
Y=20+30
Y=50
