Using a system of equations, it is found that:
- The cost of a health bar is of $1.
- The cost o a health drink is of $2.
<h3 /><h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Cost of a health bar.
- Variable y: Cost of a health drink.
You buy 4 health bars and 3 health drinks for $10, hence:
4x + 3y = 10.
Your friend buys 6 health bars and 2 health drinks for $10, hence:
6x + 2y = 10
2y = 10 - 6x
y = 5 - 3x.
Replacing on the first equation:
4x + 3y = 10
4x + 3(5 - 3x) = 10
-5x = -5
5x = 5
x = 1
Then:
y = 5 - 3x = 5 - 3 = 2.
- The cost of a health bar is of $1.
- The cost o a health drink is of $2.

Answer:
120 lb of soybean meal
200 lb of cornmeal
Step-by-step explanation:
S = pounds of soybean meal
C = pounds of cornmeal
S + C = 320 → C = 320 – S
0.16S + 0.08C = 0.11 × 320 = 35.2
16S + 8C = 3520
16S + 8(320 – S) = 3520
16S + 2560 – 8S = 3520
8S + 2560 = 3520
8S = 960
S = 120
C = 320 – 120 = 200
Answer:
2
Step-by-step explanation:
Diameter = 14
Radius = 7 inches
Volume = (4/3)×3.14×7³ = 1436.026667 inches³
1436.026667 ÷ 693 = 2.072187552
