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
