In 4 days, because 5 x 4 = $20
30 + 20 = $50
9 x 4 = $36
36 + 14 = $50
4 was multiplied then added in order to find out Erins, and Andres.
r · 7 ≤ 21 [r multiplied by 7 is less than or equal to 21]
7r ≤ 21
[If you wanted to solve it]
7r ≤ 21 Divide 7 on both sides to get "r" by itself

r ≤ 3
Your answer should be 1.7
I hope this helps! Good Luck!

Hi there!
The correct answer is 6.25 times.
This is how you get there:
1) First off, you are going to need to have the same unit (either cm or mm). I used millimeters for this problem. 25cm=250mm
2) This next part is very easy to get wrong. You need to figure out what you are dividing, and by what. Simply look at the problem. <span><em>"How much longer is the guinea pig than her fish?" </em>This shows what numbers you should be getting. The guinea pig is 250mm long, where the fish is only 40. This means that her guinea pig should be larger. 250÷40=6.25
If you did this problem the other way, you would've ended up with .16. If you put the sizes into perspective, you will notice that this is highly unlikely.
I hope that I have been able to simplify this problem for you!
