A parent deposits $2000 into their child's bank account. The account earns 4%
qaws [65]

Answer:

A = 2000(1.04)^t

Step-by-step explanation:

Using the compound interest formula;

A = P(1+r)^t

P is the principal = $2000

r is the rate = 4% = 0.04

On substituting

A = 2000(1+0.04)^t

A = 2000(1.04)^t

Hence the required expression is A = 2000(1.04)^t

Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower
Korolek [52]

The question is incomplete. The complete question is :

Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower and gas, and his revenue is $25 per lawn. At what point will Nate's revenue exceed his expense?

Cost of lawn mower = $ 200

Cost of gasoline = $ 2 per lawn

Solution :

Given :

Cost of the lawn mower = $ 200

The cost of gasoline expense for one lawn = $ 2

The revenue generated for one lawn = $ 25

So let the number of lawn to be mowed = x

Therefore the total expenses = $200+2x$

So, the total revenue = $25x$

The point for which the revenue will exceed the total expenditure will be :

$25x \geq 200+2x$

So at x=9,  \ 225 > 218

Thus the revenue exceeds the total expenditure after mowing 9 number of lawns.
