Question

Charles had 42.3 feet of twine to tie off

some packages. He used 6.6 feet each on
4 packages and 7.5 on another package.
How much twine did Charles have left?

Answer 1

To solve this problem, we need to add up the total amount of twine Charles used and then subtract it from the total amount he had.

Charles used 6.6 feet for each of the four packages, so he used a total of 6.6 * 4 = 26.4 feet for those packages.

He also used 7.5 feet for another package.

Therefore, the total amount of twine Charles used is 26.4 + 7.5 = 33.9 feet.

To find out how much twine Charles had left, we need to subtract the amount he used from the total amount he had:

42.3 - 33.9 = 8.4 feet

Therefore, Charles had 8.4 feet of twine left.
