Fred earns $ 45 mowing the lawn. He spends $ 5 on music, and puts half of what's left in a savings account. He then gets another $ 10 for washing his neighbor's car. First, write the expression that represents the number of dollars Fred keeps (and does not put in his savings account), and then simplify.

$30

Step-by-step explanation:

Given that :

Amount earned for mowing = $45

Amount spent on music = $5

Amount earned for washing neighbor's car = $10

Amount saved = half or remaining amount

Amount of dollars Fred keeps =

Amount Fred keeps:

[(Amount earned - amount spent) / 2] + $10

[($45 - $5) / 2] +

($40 / 2) + $10

= $20 + $10

= $30
