Question 6.6.

Olayinka is participating in a bowl-a-thon to raise money for the local hospital. A sponsor will pay Olayinka $2 plus $0.10 per pin, x, that she knocks down. Which equation should Olayinka use to find the total amount of money she raised?



(Points : 5)


B = (2 – 0.10)x




B = 2x + 0.10




B = 0.10x + 2




B = (0.10 + 2)x

Verified Answer :

\(8x+4y=48 \\ -8x-8x \\ 4y=-8x+48 \\ /4 /4 \\ y=-2x+12\)

B=0.10x + 2

Slope - intercept form: y = mx + b

8x + 4y = 48
8x - 8x + 4y = 48 - 8x
4y = -8x + 48
4            4
y = -2x + 12

Answer: y = -2x + 12

First you subtract 8x on both sides to get 4y alone giving you 4y = -8x + 48. Then you divide by 4 on both sides to get y alone which leaves you with y = -2x + 12
