Question

Hannah has $482.75 in her savings account. She would like her account balance to be more than $1,250 before she buys a cell phone. Hannah plans to save $85.25 a month. How many months will it be until she can buy a cell phone? (Hint:Write and solve an inequality that represents this situation.) *

Answer 1

The inequality equation would be 482.75+82.25x1250 subtracting the amount that Hannah already has from the goal would amount to 767.25, therefore she only needs to save up to equal or more than this amount. Dividing this by 82.25 would then give us how many months this would take equal or greater than 9.33 months.
