Answer:
$78.72
Step-by-step explanation:
To find 30% of the original value, we need to turn this percentage into a decimal or a fraction and then multiply it by the original value

- ($262.40)(0.30) = $78.72 is the amount saved
First hour: 3 = 3¹
Second hour: (3) x 3 = 3²
Third hour: (3 x 3) x 3 = 3³
Fourth hour: (3 x 3 x 3) x 3 = 3⁴
Do you see the pattern? <em>
where n is the number of hours</em>
Answer: 3³,
1 2/3 . Hope this helps ;)
