Answer:
3 months
Step-by-step explanation: Let after m months they saved same amount of money.
Given,
Saving of Jaclyn = $ 120,
Amount earned by him/her per month = $ 40,
So, the total amount contained by him/her in m months = Saving + earning for m months
= 120 + 40m,
Similarly, saving of Pedro = $ 180,
Amount earned by him/her per month = $ 20,
So, the total amount contained by him/her in m months = 180 + 20m
Thus, we can write,
120 + 40m = 180 + 20m
40m = 180 + 20m - 120
40m - 20m = 60
20m = 60
⇒ m = = 3.
Hence, it will take 3 months before which Jaclyn and Pedro have saved the same amount of money.
Answer:
160 sandwiches/hour
Step-by-step explanation:
To find his unit rate, divide 400 by 2.5, since he can make 400 sandwiches in 2.5 hours:
400/2.5
= 160
This means he can make 160 sandwiches in 1 hour.
So, his unit rate is 160 sandwiches/hour
