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

Answer: 6 weeks.

Your explanation

You want to take 11 and multiply 11 by 6 and get 66. Then add 66 and 30 and get 96. That's more then enough for the skateboard. 5 weeks will only equal 85, so 6 weeks is the least you can do.
