There are 480 dishes that need to be rinsed. juan can rinse them in 80 minutes by himself. it will his friend kevin 120 minutes to rinse these dishes. how long will it take them if they rinse these 480 dishes together ?

48 minutes.

Step-by-step explanation:

Number of dishes rinsed by Juan in 1 minute

= 480/80

= 6

Number of dishes rinsed by Kevin in 1 minute

= 480/120

= 4

Number of dishes rinsed by Juan and Kevin in 1 minute

= 6 + 4

= 10

Hence, time taken by Juan and Kevin to rinse the dishes

= 480/10

= 48 minutes.

Hence It will take 48 minutes for them to rinse the dishes.

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
