2 answers:
Answer:
- 18 lollipops
- 8 bags of chips
Step-by-step explanation:
The equations we want to graph are one for the revenue, and one for the number of items sold.
__
<h3>revenue</h3>The revenue from each lollipop is $1, so the revenue in dollars from selling x of them is 1·x = x. The revenue from each bag of chips is $1.50, so the revenue from selling y of them is 1.50·y = 1.5y. The total revenue from selling x lollipops and y bags of chips is ...
x +1.5y = 30 . . . . . dollars
__
<h3>item count</h3>The total number of items sold is ...
x + y = 26
__
<h3>solution</h3>The graph shows the solution to these two equations is ...
(x, y) = (18, 8)
The number of lollipops sold is 18; the number of bags of chips sold is 8.

Answer :
Depends on the rate compound interest is accrued. See answers.
Step-by-step explanation:
We need the compound interest formula which is:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
It doesn't say how frequently the interest is compounded, so we will do monthly, quarterly, and yearly.
MONTHLY
So we know the car costs $25,480 and he made a down payment of $10,000. By subtracting the down payment from the purchase price we find the loan amount.
$25,480 - $10,000 = $15,480
P = 15,480
r = 4.75% = .0475
n = 12 (12 months in a year)
t = 2
Plug everything into the compound interest formula.
Mr. Lee paid $17,016.14 when the bill came due at 2 years with interest compounded monthly.
QUARTERLY
P = 15,480
r = 4.75% = .0475
n = 4 (4 quarters in a year)
t = 2
Mr. Lee paid $17,013.20 when the bill came due at 2 years with interest compounded quarterly.
YEARLY
P = 15,480
r = 4.75% = .0475
n = 1
t = 2
Mr. Lee paid $16,985.53 when the bill came due at 2 years with interest compounded yearly.
