Question

Janice is trying to earn $30 to buy a necklace. She has saved $5.25. She earns $2.25 per hour weeding her grandmother's garden and she earns $5.50 per hour selling seashells at the flea market. Will Janice have enough to buy the necklace if she works in the garden for 2 hours and at the flea market for 4 hours? Use the inequality 2.25y + 5.50z + 5.25 ≥ 30.

Answer 1

Explanation:

Answer:

Yes

Step-by-step explanation:

2.25y + 5.50z + 5.25 ≥ 30

where y is the hours spent weeding and z is the hours spent selling seashells

y = 2 and z = 4

2.25(2) + 5.5(4) +5.25 ≥ 30

4.50 + 22 + 5.25 ≥ 30

31.75 ≥ 30

This is true so she has enough money

Answer 2

Yes

Explanation:

2.25y + 5.50z + 5.25 ≥ 30

where y is the hours spent weeding and z is the hours spent selling seashells

y = 2 and z = 4

2.25(2) + 5.5(4) +5.25 ≥ 30

4.50 + 22 + 5.25 ≥ 30

31.75 ≥ 30

This is true so she has enough money
