How much less per hour does Shaquana earn than Vani?

Answer 1

Shaquana earns $9.00 less per hour than Vani, with Shaquana's hourly rate being $19.80 and Vani's being $28.80.

Step-by-step explanation:

To calculate how much less per hour Shaquana earns than Vani, we first need to determine Shaquana's hourly rate. Shaquana earned $653.40 for 33 hours of work, so to find her hourly rate, we divide her total earnings by the number of hours worked:

Shaquana's hourly rate = $653.40 / 33 = $19.80

From the equation y = 28.8x, we know that Vani earns $28.80 for each hour of work. Now we can find the difference in their hourly rates:

Difference in hourly rate = Vani's rate - Shaquana's rate

Difference in hourly rate = $28.80 - $19.80 = $9.00

Therefore, Shaquana earns $9.00 less per hour than Vani.
