Step-by-step explanation:
Just took the test. Hope this helps
Answer:
312 ft
Step-by-step explanation:
The steps are as follows :
1. The problem can be described as an equation
2. Convert all values on the left side into their equivalent fractional values
3. Combine like terms
4. Multiply both sides by the reciprocal of 13/8 to isolate variable X
5. Simplify
6. Check answer by using it in the original equation
To answer this question you should begin with the coin that has a higher value. If you start with the dime and then just add the correct number of pennies to total $0.40, you will see that you will need 3 dimes ($0.30) and 10 pennies ($0.10).
I used a guess and check strategy starting with 2 dimes.
If we let x as candy A
y as candy B
a as dark chocolate in candy a
b as dark chocolate in candy b
c as caramel
d as walnut
P as profit
we have the equations:
a + c = x
2b + d = y
a + 2b ≤ 360
c ≤ 430
d ≤ 210
P = 285x + 260y
This is an optimization problem which involves linear programming. It can be solved by graphical method or by algebraic solution.
P = 285(a + c) + 260(2b +d)
If we assume a = b
Then a = 120, 2b = 240
P = 285(120 + 120) + 260(240 + 120)
P = 162000
candy A should be = 240
candy B should be = 360
