Question

Sophia needs $47 to go on a field trip. She has saved $11.50. She earns $6.50 per hour cleaning her neighbor's garden, and she earns $5.25 per hour selling cakes at a store. Can Sophia 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 + 11.50 ≥ 47.)

Yes, because the total will be $48
Yes, because the total will be $52
No, because the total will be $42
No, because the total will be $39

Answer 1

Ok so um first set it up

6.50x + 5.25y + 11.50 ≥ 47

So

X = 4

And

Y = 2

So do the multiplication first

6.50 x 4 = 26

And then

5.25 x 2 = 10.5

So now it’s
26 + 10.5 + 11.50 ≥ 47

So now jus simplify to see if it’s enough


26 + 10.5 = 36.5

Then

36.5 + 11.50 = 47

So it’s a
