Answers and Step-by-step explanations:
(a)
We need to figure out the amount (or total cost) for each size candy given that they sell a certain number of each box. For the small box, we're given the cost is $4.70, while the large box is $7.00.
We buy x of the small box, so the total amount should be 4.70 * x, or just 4.70x. We buy y of the large box, so the total amount should be 7.00 * y, or just 7y.
So on the table, the top value should be 4.70x, and the bottom value should be 7y.
(b)
The total number of boxes sold was 45 boxes. Remember that x boxes were small and y boxes were large. Since the number of small boxes plus the number of large boxes is equal to the total of 45, we can write:
x + y = 45
(c)
The total cost was $269, so we can write this as the sum of the amounts that we found in part (a):
4.70x + 7y = 269
Recipes 1 and 2 would taste the same but Recipe 3 would taste different. This is because both Recipe 1 and 2 use a 2:3 ratio, while Recipe 3 uses a 3:4 ratio.
The ratio for Recipe 1 is 4:6 and for Recipe 2 is 6:9, which when simplified is 2:3.
Meanwhile the ratio for Recipe 3 is 9:12, which simplified is 3:4.
Answer:
$108
Step-by-step explanation:
Let n be the cost of a keychain, then the cost of a T-Shirt would be 4n. We can use this to set up an equation...
4n+n=135
Combine like terms
5n=135
Divide both sides by 5
n=27
Now we need to find how much she made from selling T-Shirts...
4n=4(27)=$108
1) 48
2) 168
3) 400
4) 126
5) 48
6) 154
7) 270
8) 144
I think the answer is A,4.25 cm
