Question

Cody worked 16 hours last week at the grocery store His friend Sophie worked nine less that twice the number of hours that Cody did.If Cody made $156.80 and they both make the same hourly rate,how much did sophie make

Answer 1

Answer: Sophie made $137.2 that week

Step-by-step explanation:

First, find how much money Cody makes an hour with this equation 16t = 156.80 (t = how much they get paid an hour) => 156.80/16 = 9.8

Cody makes 9.8 dollars an hour.

Now, we find out how much Sophie worked. it states "Sophie worked nine less that twice the number of hours that Cody did" so it should be 16-9 multiplied by 2

Sophie worked 2(16-9) = 14 hours

Finally, multiply the hours worked times the amount she earns an hour 14x9.8= 137.2 dollars

Sophie made $137.2 that week
