Inequality:


Answer:

Answer 1

See below :)

Explanation:

13:
So we know that he only has $65 to spend, so let's write an inequality for this problem using j as the variable for the price of the jeans:

65 > 18 + 14 + j

Simplified: 65 > 32 + j

Shemar can spend up to $33 on a pair of jeans.

14. We know that Blake needs to earn at least $200 to buy what he wants, so let's write an inequality for this using l as the variable for the number of lawns he needs to mow:

200 < 12l

Blake needs to mow 16.6667 lawns, but since you can't mow a fraction of a lawn, we round up to 17 lawns. He needs to mow 17 lawns.

15. Annabelle wants to save $1,250 by the end of summer, let's use h for the number of hours she needs to work to meet her money goal with the $100 bonus at the end of the summer:

1,250 < 8.5h + 100

Annabelle needs to work 135.3 hours, or, rounded, 136 hours.

Hope this helps! :)
