how could you have 0.87$ with the least number

This absoulutly suck whoever made this i am sry

To have $0.87 with the least number of coins, you can use the following combination:

5 dimes ($0.10 each) = $0.50
3 pennies ($0.01 each) = $0.03
2 quarters ($0.25 each) = $0.50
1 nickel ($0.05 each) = $0.05

Adding these coins together: $0.50 + $0.03 + $0.50 + $0.05 = $1.08

Since $1.08 is more than $0.87, you cannot have exactly $0.87 using the least number of coins.

Is that 87 percent (87%)?

87% of what?
