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?

47 - 11.50 = $35.50 needs to be earned.

If she works 6 hours:
6.50 x 4 = 26
5.25 x 2 = 10.50

26 + 10.50 = $36.50 how much she would earn by working 6 hours.

when you add the amount of money she would earn for working 6 hours $36.50 plus the money she had already had saved up $11.50 the total amount of money she would have is $48.00

So, yes. She would be able to go on the field trip if she worked at both jobs to 6 hours.
