Answer:
D. 4s = 16
Explanation:
We are given that a T-shirt is 4 times the price of the sock.
This means that if we multiply the price of sock by 4, we will get the price of the T-shirt.
In equation form:
price of T-shirt = 4*price of sock
We are given that:
cost of the pair of socks is "s".
cost of T-shirt = 16
Substitute in the above equation, we get:
16 = 4s

Answer:
- Burgers - $8.29 and fries - $4.39
Step-by-step explanation:
<u>Let burgers - b, fries - f</u>
- 8b + 3f = 79.49
- 12b + 6f = 125.82
<u>Double the first equation and subtract the second equation:</u>
- 16b + 6f - 12b - 6f = 2(79.49) - 125.82
- 4b = 33.16
- b = 33.16/4
- b = 8.29
<u>Find f:</u>
- 8(8.29) + 3f = 79.49
- 3f = 79.49 - 66.32
- 3f = 13.17
- f = 13.17/3
- f = 4.39
