Step-by-step explanation:
From the statement:
M: is total to be memorized
A(t): the amount memorized.
The key issue is translate this statement as equation "rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized"
memorizing rate is 
.
the amount that is left to be memorized can be expressed as the total minus the amount memorized, that is 
.
So we can write
And that would be the differential equation for A(t).
Answer:The total cost for the car including tax is $27423.75
Step-by-step explanation:
The initial price of the car that you want is 25,750. If the sales tax rate is 6.5%, it means that the amount of sales tax would be
6.5/100 × 25750 = 0.065 × 25750 = 1673.75
The total cost for the car including tax would be the sum of the initial cost of the car and the amount of tax. It becomes
25750 + 1673.75 = $27423.75
It would be 2/3 because 2 divided by 3 on a calculator is .6667
