PLEASE HELP!!! Douglas bikes to 7.68 miles to work 4 days of each week. (He also must bike back home.) On the other 3 days, he rides his bike along a trail that loops back to where he started and is 15.8 miles long. How many miles does Douglas bike each week?

108.84

Step-by-step explanation:

7.68*2=15.36 miles every day for work

15.36*4=61.44 miles on the 4 work days

15.8*3=47.4 miles on the other 3 days

61.44+47.4=108.84 miles a week

b.) divide by -5.

step-by-step explanation:

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
