Question

1) find the total cost to purchase $1,200 in traveler's checks if a 1 3/4% fee is charged.

2)find the total value of 17 rolls of nickels and 23 rolls of pennies if each nickel roll is $2 and each penny roll is $.50.

Answer 1

1) 1200(1.0175)=1200+21=$1221

2) 17 rolls of nickels worth $2 per roll

23 rolls of pennies worth $.50 per roll

total value = 17(2) + 23(1/2) = 34 +11 1/2

= 45 1/2 = $45.50
