Answer:
1 cookie = $1.25 1 cake = $15
Step-by-step explanation:
set up a system of equations:
let x = 1 cookie
let y = 1 cake
3x + 5y = 78.75
8x + 2y = 40
I multiplied the first equation by 2 to get: 6x + 10y = 157.50
I multiplied the second equation by -5 to get: -40x - 10y = -200.00
If you add both equations, the y-terms will be eliminated
-34x = -42.50
x = 1.25
Plug in 1.25 into equation to find value of y: 8(1.25) + 2y = 40
10 + 2y = 40
2y = 30
y = 15
If you eat two of your muffins, you will consume 408 calories.
<h3>
How many calories are in a muffin?</h3>
Here a recipe says that yields 12 muffins with 340 calories per muffin, so the total number of calories for the recipe is:
C = 12*340 cal = 4,080 cal.
If you followed the same recipe, then the total number of calories of your 20 muffins is 4,080 calories.
Assuming that those calories are evenly distributed among the 20 muffins, then the number of calories each muffin will have is given by the quotient:
4,080cal/20 = 204 cal.
Each of your 20 muffins will have 204 calories, then if you eat two of these, you will consume 408 calories.

Answer:
<h2>$267,536,000</h2>
Step-by-step explanation:
Step one:
given data
total ounces=500,000
cost per ounce= $460
total amount of the ounce= 500,000*460= $230000000
Time t=3years
rate= 5.17%= 0.0517
Step two:
The inflation we have a compounding effect on the amount
$230000000
A=P(1+r)^t
A=230000000(1+0.0517)^3
A=230000000(1.0517)^3
A=230000000*1.1632
A=$267,536,000
<u>They will receive a total of $267,536,000</u>
Answer: Distance between dolphin and helicopter = 93.5 feet
Explanation:
Distance at which dolphin swimming below the ocean= (-) 18 feet
(it is represented as the negative number as it denotes the distance below the ocean)
Distance at which helicopter is above the ocean = (+) 75.5 feet
(it is represented as the positive number as it denotes the distance above the ocean)
Distance between dolphin and helicopter = 75.5 - (-18) feet
= 75.5 + 18 feet
= 93.5 feet
