Sasha works as a babysitter. She charges $20 for the job plus an additional $5 per hour. Sasha and her family will soon be leaving for vacation, and Sasha would like to have at least $70 for spending money. How many hours does Sasha need to work to earn her goal?

She would have to work 10 hours.

Step-by-step explanation:

She charges 20 to do the job but 5 for every hour well she already has 20 cause thats what she charges to do the job and sine 5x10=50

50+20=$70 so she will need to work 10 hours to be able to spend $70 on trip

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
