carol wants to earn at least $150.00 for her charity while running in a race. she will earn $20.00 for participating plus $7.00 for each mile she runs. if m represents the number of miles shre runs, which inequality represents the money carol wants to earn?

I've answered several of your questions. Now it's your turn.
I'll be glad to check your answer. 
i do not want an answer i just don't get how to do this problem. i have a packet and i do the ones i get and ask for help with the ones i dont. i just ask for an explanation on how to do the questions that i do not understand.

for this question, if carolwants to earn $150.00 but she already has earned $20.00 would she subtract that or just look for an inequality

20 + 7m < 150

but if she wants to earn 150 and she already has 20 would she subtract 20 from 150? how is it 20+7m<150

7m < 150  20
We both posted the same inequality.
