Distribute on the left side
7.4a+22.2=3.2a+43.2
Subtract 3.2a from both sides
4.2a+22.2=43.2
Subtract 22.2 from both sides
4.2a=21
Divide both sides by 4.2
a=5

Answer:

$60775000

Step-by-step explanation:

Question ask for how much $ you lose in 52 weeks.

You're given that computer is down 2.75 hours per week. Each of those hours cost you $425000.

In other word, you loose 2.75×425000=$1168750 each week.

If 1 week cost you $1168750,

then 52 weeks, you'll lose 1168750×52=$60775000
