2, (double) 4, (double) 8 (double) 16, So 16 in week 4
2+4+8+16 = 30
There are no answer choices but if he drove 5 miles in 15 minutes and then traveled about at the same speed in 30 minutes which means he drove 5 more miles which makes it 10 so he is driving at 20mph
-hope it helps
There are 60 minutes on a clock. each minute would be 360 / 60 = 6 degrees.
5:15 to 5:25 is 10 minutes.
The angle would be 10 x 6 = 60 degrees.
For this case we have the following equation:
c + b = 55
Where,
c: number of CDs
b: number of books
For c = 30 we have:
30 + b = 55
From here, we clear the value of b.
We have then:
b = 55-30
b = 25
Note: observe in the graph that when the value of c is 30, the value of b is 25.
Answer:
the amount Alison may spend on books in March if she spends 30 on CDs is:
b = 25
