<span>Let n = the number of pages not read
Then the number of pages read = n/4 + 3
Since the total number of pages is 193, we have
n + n/4 + 3 = 193
5n/4 = 190
n = 152
At 8 pages per day it will take 152 pages/ 8 pages/day = 19 days

answer the cost will be higher
Answer:
415.63 minutes
Step-by-step explanation:
Growth can be represented by the equation . We can find the rate at which it grows by using t=25 minutes and or double the amount at that time. The first step we always take is to divide by A.
To solve for r, we will take the natural log of both sides and use log rules to isolate r.
We know so we were able to cancel it out and divide both sides by 25.
We solve with a calculator
We change 0.0277 into a percent by multiplying by 100 to get 2.77% as the rate.
The equation is
.
We repeat the step above substituting A=5,000,000, =50, and r=0.02777. Then solve for t.
t=415.63 minutes
