Hint 1 of 2
A dollar IS 100 cents — so cents and 'percent of a dollar' are the very same number.

Hint 2 of 2
That means you don't need a percent calculation at all: just total the coins in cents.
Show solution
Approach: read cents directly as percent (a dollar = 100 cents)
- The trick: 'percent' means 'out of 100,' and a dollar is exactly 100 cents. So however many cents you have IS the percent of a dollar — no division needed.
- Total the coins: 1 + 5 + 10 + 25 = 41 cents, which is 41% of a dollar.
- You'll see it again: any time the whole is 100 (100 cents, 100 students, a 100-point test), counts and percents are the same number.
