1 half dollar + 1 quarter - 2 dimes
Eduardwww [97]

Answer:

55 cents.

Step-by-step explanation:

First, we start off with a half dollar (50 cents), and add a quarter (25 cents). 50 + 25 = 75. Next we take two dimes (each dime being 10 cents). 10 + 10 is 20, so we have twenty cents in dimes. It says to subtract the 2 dimes from our current number 75 minus 20 is 55. Therefore, we have 55 cents left. (If needed, that is 1 half dollar and 1 nickel.)

Hope this helps! :D
