Question

Ken has a total of 74 notes. They are either $2 or $5 notes. He has 16 more pieces of $5 notes than $2 notes. Find the total value of all his notes.

Answer 1

$283

Explanation:

Let,

x - for $2 notes

x + 16 - for $5 notes

EQUATION:

(x) + (x + 16) = 74

2x = 74 - 16

2x = 58

x = 29

SUBSTITUTE

x = 29 pieces of $2 notes

x + 16 = 29 + 16 = 45 pieces of $5 notes

TOTAL VALUE IS:

(29 x $2) + (45 x $5) = $283
