(That is, write an equation of the form a ⋅p+b⋅n=c that satisfies the constraints of the problem.) The only other information given is this:Suppose you'd like to purchase a candy bar that costs $0.96 using only pennies (worth $0.01 each) and nickels (worth $0.05 each). Let p represent the number of pennies you used to purchase the candy bar. Let n represent the number of nickels you used to purchase the candy bar. I am completely unsure about how to solve thisarrow_forward
