Rob is saving to buy a new MP3 player. For every $15 he earns babysitting, he saves $6. On Saturday, Rob earned $75 babysitting.

First you have to see how many time 15 goes into 75, which is 5 so for every time 15 goes into 75 it would be another $6, so the answer is 6 * 5 which is $30. Hope this helps!

kaheart [24]

Answer:

Margie spent 60% of time in doing science Homework

Step-by-step explanation:

Given:

Time spent in doing maths homework = 25 minutes

Time spent in doing science homework = 60 minutes

Break Time = 15 minutes

To Find:

A percent to represent the portion of time that Margie spent on science homework = ?

Solution:

Let the portion representing the portion of time that Margie spent on science homework be x

The total time spent in doing both maths and science homework and in break time = Time spent in doing maths homework + Time spent in doing science homework + Break Time

The total time spent in doing both maths and science homework and in break time = 25 +60 +15 = 100 minutes

Then

x = $\frac{\text{time spent in doing science home work}}{\text{total time spent}} \times 100$
