Answer:
$-17.82
Step-by-step explanation:
he has $-17.82 because 30.85(the amount he has)-48.67(the amount he paid for) = -17.82
$0.25 = 5 bottles
Divide both sides by 5:
$0.05 = 1 bottle
Last week: $12.75
12.75 = 0.05b where b represents bottles
Divide all by 0.05 to get b alone:
255 = b
We can solve this problem by rule of 3:
$30 (taxes)------------$100
x-----------------------$3,680
x=($30*$3,680) / $100=$1,104
