If 1 bottle of water is 5 cents and i have 16 bottles of water, how much would that be?

80 cents

Step-by-step explanation:

To answer this question, all you have to do is multiply:

16 bottles of water * 5 cents for each bottle = 80 cents total for all 16 bottles of water

Hope this helps :)

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
