Lewis wants to buy a skateboard that costs $89.99. He has $300 saved. He wants to save $11 each week until he has enough money to pay for the skateboard. The inequality 30 + 11w ≥ 89.99 represents this situation, where w is the least number of weeks Lewis has to save until he has enough money to pay for the skateboard?

Answer:

Explanation:

I'm guessing you meant to say Lewis had $30 starting.

Well since we have an inequality already, that saves time on me and I can show you how to solve!


30+11w\geq 89.99


11w\geq59.99


w\geq 5.4536

If Lewis waited 5 weeks, he'd only have 85, so we need to round up to 6 weeks, where he'd have $96. Hope this helps!
