Wouldnt u add all those amounts of money then divide it by 40 so it would give u the amount of money needed to cover her costs?
Answer:
20
Step-by-step explanation:
Number of paperback books = 4
Percentage of total books that were paperbacks = 20%
Let total number of books = x
Hence,
20% of total books = paperback books
20% of x = 4
0.2 * x = 4
0.2x = 4
0.2x / 0.2 = 4 / 0.2
x = 20
Total number of books = 20
Answer:
the interest owed is 1684.8
Step-by-step explanation:
Formula for simple interest =
I = Prt, where P is amount borrowed, r for interest rate and t for time.
Since the first three years is 1.6% interest we can write:
I = 15600 x 0.016 x 3
= 748.8
Then for the following 3 years the interest rate is 2%:
I = 15600 x 0.02 x 3
= 936
Adding the values gives us 1684.8
13.45 x $4.30= $57.835 ≈ $57.84
13.45 x 40.2=540.69 miles
