Answer: I believe his earnings would be 187$ once he teaches 7 classes.


Step-by-step explanation:

$187-$68=$111

17 x ? = 119

(take the 17$ which is the amount of money he'll earn each class and divide by 111. as seen below:

$111/17$=$6.5 (round to $7)

(you then plug in the 17 for 7 x ? = 119)

7x17=119

now you have to add the 68$ that he will get per month.

119+68=187

then you get 187$ which he had spent on the certificate
