heeeeeeeeeeeelllllllllllllllppppppppppp pppppppplllllllllllzzzzzzzzzzzz

Clara needs $52 to go on a field trip. She has saved $16.50. She earns $6.50 per hour cleaning her neighbor's garden, and she earns $5.25 per hour selling cakes at a store. Can Clara go on the field trip if she works at the garden for 4 hours and at the store for 2 hours?

[Use the inequality 6.50x + 5.25y + 16.50 ≥ 52]

Yes, because the total will be $53
Yes, because the total will be $59
No, because the total will be $42
No, because the total will be $49

Answer 1

x = cleaning gardens = 4 hours
y = selling cakes = 2 hours

Plug in to corresponding variables.

6.50x + 5.25y + 16.50 ≥ 52

6.50(4) + 5.25(2) + 16.50 ≥ 52

Simplify.

6.50(4) = 26
5.25(2)  = 10.5
16.50 = 16.50

26 + 10.50 + 16.50 = 53

53 ≥ 52 (True)

Yes, because the total will be$53 is your answer


hope this helps
