Darshon had 85% of a dollar. at the school store he spent 2/5 of a dollar on a pen and another 0.20 on a pencil. how much money did darshon have after going to the store

Hello!

A dollar is 1.00

85% of 1 is: 0.85.

Now, divide 0.85 by 5:

0.85/5 = 0.17

Multiply that by the numerator:

0.17 • 2 = 0.34

Subtract:

0.85 - 0.34 = 0.51

0.51 - 0.20 = 0.31

So, Darshon had 31 cents left after going to the store. (0.31 of a dollar). (That can also be written as 31%)

I really hope this helped you! :)
