you have a part time job. you work 3 hours on friday and 6 hours on saturday. you also receive an allowance of $20 per a week. y
klemol [59]
$92/week is the amount of money you gained from work combined with your $20/week allowance money. 

92 - 20 = 72 (total money made per week subtract allowance money leaves money made from work)
Thus, you make $72/week at your part time job.

You work a total of 9 hours. (3hrs on Fri & 6hrs on Sat added together)
72/9 = 8 (total amount of money made divided by the 9 hrs you worked for - gives amount of money you make per hour)
Thus, you make $8/hr at your part time job.

Tema [17]

Answer:

10

Step-by-step explanation:

2/3 can be multiplied by 5 to equal 15ths since we can know 15 (seconds number fraction) is 5 times the originals (first numbers fractions)

This equals to 10/15 and means that with 1/15th on each 10 sandwiches can be made.

The answer gives it straight forward but explanation gets in depth

Edit: I saw your answer and yes it equals 10 but you multiply what it is a fraction of too.

2/3

x5

10/15
