Mack’s hourly wage is raised from $12.10 per hour to $13.35 per hour. He works 40 hours per week. How much more does he earn per week at this new rate?
40(13.35 - 12.10) = x
$50 more each week
To calculate how much more Mack earns per week at the new rate, we need to find the difference between his old and new wages.
First, let's calculate his old weekly earnings:
Old hourly wage = $12.10
Old weekly earnings = Old hourly wage * Hours worked per week
= $12.10 * 40 hours
Next, let's calculate his new weekly earnings:
New hourly wage = $13.35
New weekly earnings = New hourly wage * Hours worked per week
= $13.35 * 40 hours
Now we can find the difference in his weekly earnings:
Difference in weekly earnings = New weekly earnings - Old weekly earnings
By substituting the values into the equation, we get:
Difference in weekly earnings = ($13.35 * 40 hours) - ($12.10 * 40 hours)
Simplifying this equation:
Difference in weekly earnings = $534 - $484
Therefore, Mack earns $50 more per week at this new rate.
