Intro:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
If she keeps that rate she will be making 18 dollars every week. You can get that if you do the 6 dollars times the number of days she goes every week which is 3 so 3*6 is 18.
Now assuming that there are 13 weeks in summer, we will do $18 times the 13 weeks to get $234.
