Answer:

$0.20

Step-by-step explanation:

When finding the mean, you add up all the numbers, then divide by how many numbers there are. So you add up all the costs and divide them by 7.

Week 1: 3.3

Week 2: 3.1

Then ofcouse, to find the difference you subtract 3.3 by 3.1 and you get $0.20

lions [1.4K]

Answer:

x _> 9 I dont have the symbol on my phone so I just put the greater than sign there

Step-by-step explanation:

1. Subtract 3 from both sides

5x > 48 - 3

2. simplofy 48 - 3 to 45

5x > 45

3. Divide both sides by 5

x > 45/5

4. Then simplify 45/5 to 9 which gives us the answer

And again I dont have the sign thats why I used the greater than sign
