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. Yes, because the total will be $26.50. Yes, because the total will be $31.75. No, because the total will be $25.25. No, because the total will be $46.50.

Answer 1

yes

Explanation:

because the total will be $31.75.

Answer 2

Yes, because the total will be $31.75

Explanation:

Let

x -----> number of hours weeding grandmother's garden

z ----> number of hours selling seashells at the flea market

we know that

The inequality that represent this situation is

`2.25x+5.50z+5.25\geq30`

so

For x=2 hours, z=4 hours

substitute in the inequality

`2.25(2)+5.50(4)+5.25\geq30`

`4.50+22+5.25\geq30`

`31.75\geq30` -----> is true

therefore

Janice will have enough to buy the necklace
