You go to a convenience store to buy candy and find the owner to be rather odd. He allows you to buy pieces in multiples of four, and to buy four, you need $0.23. He only allows you to do this by using 3 pennies and 2 dimes. You have a bunch of pennies and dimes, and instead of counting them, you decide to weigh them. You have 636.3 g of pennies, and each penny weighs 3.03 g. Each dime weighs 2.29 g. Each piece of candy weighs 10.23 g. 

a. How many pennies do you have?

b. How many dimes do you need to buy as much candy as possible?

c. How much should all these dimes weigh?

d. How many pieces of candy could you buy? (number of dimes from part b)

e. How much would this candy weigh?

f. How many pieces of candy could you buy with twice as many dimes?
