Answer:

600 Cheese and 900 Pepperoni

Step-by-step explanation:

Setup the equation with 2c(Cheese) + 2.5p(Pepperoni) = $3450(Total Made).

In addition to the equation c + p = 1500(Number of pizzas sold)

Using the second equation (c + p = 1500) solve for one of the variables.

Lets use :

  1. p = 1500 - c
  2. Plus this equation into the original equation, 2c + 2.5(1500 - c) = 3450
  3. Distribute 2.5, 2c + 3750 - 2.5c = 3450
  4. Combine like terms -0.5c + 3750 = 3450
  5. Solve for c: c = 600
  6. Plus 600 in for c into any equation ( lets use c + p = 1500)
  7. 600 + p = 1500
  8. P = 900

How much interest is earned on $2,700 in one year if it is invested at 3%?
tester [92]
On this part, you can use the formula for compound interest: 

F = P(1+i)^n 
F = future worth of $ 
P = present worth of $ 
i=interest 
n=years 

F = 2700(1+0.03)^1 
F = 2781 

<span>So interest = 2781-2700 = $81

Mabel, Adeline and Charlie share 34500ft2 of land Mabel ownes 26%of the land area and Adeline Owens 47% of the land area . What
NikAS [45]

Answer:

<em>Charlie owns 9,315 ft2 of the land area</em>

Step-by-step explanation:

There are 34,500 ft2 of land shared between Mabel, Adeline, and Charlie.

Mabel owns 26% of the land area, that is:

26*34,500 ft2 / 100 = 8,970 ft2

Adeline owns 47% of the land area, or:

47*34,500 ft2 / 100 = 16,215 ft2

The land owned by Mabel and Adeline is: 8,970 ft2 + 16,215 ft2 = 25,185 ft2

Since the total area land is 34,500 ft2, Charlie owns:

34,500 ft2 - 25,185 ft2 = 9,315 ft2

Charlie owns 9,315 ft2 of the land area

Nolan Walker decided to buy a used snowmobile since his credit union was offering such low interest rates. He borrowed $2,700 at
stealth61 [152]

Using the formula for simple interest, it is found that he paid $119.87 in interest.

The<u> simple interest formula</u> is given by:

E = PIt

  • E is the amount of interest earned.
  • P is the principal(the amount of money invested).
  • I is the interest rate(yearly, as a decimal).
  • t is the time, in years.

In this problem:

  • Borrowed $2,700, thus P = 2700
  • Interest rate of 3.5%, thus I = 0.035
  • From December 26, 2019 to February 21, 2021, there were 423 days, thus the time in years is t = \frac{423}{365} = 1.2685

Thus, the interest paid was of:

E = PIt = 2700(0.035)(1.2685) = 119.87

$119.87.
