23 points and after grading (if the answers are actually right) I'll give you the top answer thingy

1.) If a bottle of soda pop costs $2 and a large bag of chips is $3, write an equation in standard form that models the possible combinations If you have $15. (Let p = soda pop and c = chips)

2.) If you bought only the soda in the problem above, how many bottles could you purchase?

3.) If you bought three bottles of soda pop (in the first problem), how many bags of chips could you purchase?

I need the answer and solving steps.
Don't give a long drawn out explanation of how you worked it out in the middle of everything... It's confusing and unhelpful. Show me the answers and then explain how you got it under the problem, thanks.
