Problema Solution
part of the proceeds from a garage sale was $340 worth of $10 and $20 bills, if there were 4 more $10 bills then $20 bills, find the number of each denomination
Answer provided by our tutors
let $20 bills be x & $10bills be (x+4)
20x + 10(x+4) = 340
20x +10x +40 =340
30x = 300
x = 10
$20bills = 10
$10 bills = 10+4 = 14
