Answer
Attempt 1 out of 2
Total value, 130 nickels and 120 pennies (dollars):
Total value, xx nickels and yy pennies (dollars):
To find the total value in dollars, we need to convert the number of nickels and pennies to dollars.
For the total value of 130 nickels, we can multiply the number of nickels by 0.05 (since each nickel is worth 5 cents):
130 nickels * $0.05/nickel = $6.50
For the total value of 120 pennies, we can divide the number of pennies by 100 (since there are 100 pennies in a dollar):
120 pennies / 100 = $1.20
Therefore, the total value of 130 nickels and 120 pennies is $6.50 + $1.20 = $7.70.
For the total value of xx nickels, we can multiply the number of nickels by 0.05 (since each nickel is worth 5 cents):
xx nickels * $0.05/nickel = $0.05 * xx
For the total value of yy pennies, we can divide the number of pennies by 100 (since there are 100 pennies in a dollar):
yy pennies / 100 = $yy
Therefore, the total value of xx nickels and yy pennies is $0.05 * xx + $yy.
