Suppose you receive $100 for a birthday present. Instead of depositing it in a savings
account and earning interest, you stick it under
your mattress. Each week thereafter, you add
$5 to your stash of cash. The amount of money
under your mattress is a function of the number
of weeks that have passed. Write an equation
for this scenario in STANDARD form.

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b. you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c. you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d. you spend $5 plus $10 per week until you have less than $45.
