Let the number of 40% leftover $5 notes be 4u,deon629 wrote:Pls help. TIA.

Charlie had 148 pieces of $2 and $5 notes. She spent 60% of her $5 notes to buy a bag and then her mother gave her another six $2 notes. As a result, the number of $2 notes was thrice as many as the number of $5 notes left. Find the amount of money Charlie had left.

Then originally he would had 10u of $5 notes.

Since $2 notes is 3 times of leftover $5 notes, then the number of $2 notes is 12u. (From 4u x 3)

Including the six $2 notes his mother gave, the total number of notes he had before buying the bag is 154

10u + 12u = 154

22u = 154

u = 7

Number of $5 notes left = 4u =28

Value of $5 notes = 28 x 5 = $140

Number of $2 notes left = 12u = 84

Value of $2 notes = 84 x 2 = $168

Total value = $140 + $$168 = $308 ###
