Lyle got paid to today. He used 1/2 of his check to
pay bills. He spent 30% of what was left on new clothes, and going out to eat. while he was out, he gave $20 to a salvation army charity santa on the street corner. He put 3/4 of what was left into savings. He lent his friend $15 and had $85 left. How much did he start with?

Lyle started with $1214.29.

What you have to do is work backwards from $85 dollars and add the amounts he spent to get $1214.

good luck,

Donnie

$1,200

1200/2=600
600-30% =420
420-20=400
400-75%=100
100-15=85 he had left
