Jimmy charges a flat amount of $10.00 plus $2.50 per hour to cut his neighbor's grass. It takes Jimmy 3 hours to cut his neighbor's grass.

If Jimmy's neighbor pays him for cutting his grass with a $20.00 bill, then how much change does Jimmy need to give his neighbor back?

$2.50

Step-by-step explanation:

First multiply 2.5 by 3. This equals $7.50. Then dd $10. Your total is now $17.50. Subtract this from 20 to get $2.50

it would open into a square depending on the type of envelope i’m not sure about the second part

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
