19.) What is the amount of money in a bank containing only dimes?

21.) The total cost equals the price of the tickets multiplied by eight people?

22.) What is the cost of buying several pairs of pants at $ 32.95 per pair?

Answer 1

let num of shirts=x

total cost = 24.95*x

no of dimes = x

total amount = dimes*x

no of marbles removed = x

left = 48-x

price of ticket = x

total price = 8*x
