Answer:
5⁷
Step-by-step explanation:
5*5*5*5*5*5*5
here,
count how many 5 are there - 7
so,
<u>exponential notation form:</u>
5*5*5*5*5*5*5 = 5⁷
Actually, she worked for seven hours, so I'll solve for that.
7.20 x 3 = 21.6
6.75 x 4 = 27
21.6 + 27 = 48.6
48.6 /2 = 24.3
Her average should be $24.3 If she did work six hours, just multiply 6.75 x 3 and do what I did.
