Question

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?

Answer 1

hurry 1:30

Answer 2

If we call the total money 'M' and the number of pins 'x' (as given) then we can break this into two parts:

First she gets $2 right off the top so: \[M=2\]
But she also gets 10cents per pin so \[M=0.1x\] add those together and you get \[M=2+0.1x\]
