Answer:
9 hours and 20 minutes.
Step-by-step explanation:
In one hour, Amanda can proofread 17 reports.
In one hour, Sally can proofread 28 reports.
That means together, they can proofread 45 reports in one hour.
So we need to divide the total amount of reports by how much they can read in an hour:
420/45 = 28/3 = 9 1/3
The time it takes between the two of them is 9 hours and 20 minutes.

Equation represents the difference in the number of foreign and domestic stamps Malik collected: X-34=y
equation represents the total number of stamps Malik collected:

245= X-Y
Situation :
Y= X-34
X-Y= 245
Answer:
the annual interest rate is 7.583%
Step-by-step explanation:
We are given
Summer has an offer to buy an item with a sticker price of $13,200
so, we have
P=13200
paying $460 a month for 36 months
so, we can find total amount
Let's assume
annual interest is r
total time =36 months
so, total number of years =3
Since, it is compounded monthly
so, n=12
now, we can use formula
now, we can plug values
now, we can solve solve for r
So, the annual interest rate is 7.583%
