Please help me I've been stuck on this one question and I can't find the answer to it. For four Fridays in June, Grace earned $21.50, $29.75, $32.00, and $15.25 from babysitting.

In July, she earned $8 more for babysitting four Fridays than she did in June.

What is the increase in the mean for July compared to June?

Round the answer to the nearest penny.
