Question

Aden buys 15 collectible coins per month. Caliana sells 5 coins from her collection of 100 each month. When will Aden have more coins than Caliana? Show your work.

Answer 1

let's let x = the # of months

if Aden buys 15 coins per month, they'd have 15*x, right?

Caliana starts with 100 coins, and sells 5 per month, so she has 100 - 5x coins

Aden has more coins than Caliana when 15x > 100 - 5x

solve for x

Answer 2

Answer 3

Answer 4

because we dont know how many months

Answer 5

that's right, we don't know how many months, which is why we use "x" to represent how many months

Answer 6

ok ok i getcha

Answer 7

let me think about it

Answer 8

wouldnt x be greater then 5

Answer 9

Answer 10

awesome, so when x > 5 Aden has more coins, so Aden has more coins after 5 months have passed, which solves our problem
