Answer:
$3200
Step-by-step explanation:
The total area of land is 30 acre. Let x represent the area in acre that corn is planted and y represent the area in acre that wheat is planted. Therefore:
x + y = 30 (1)
Also, the farmer can spend at most $750 on seeds. Corn cost $15 per acre, maize cost $30 per acre. Hence:
15x + 30y ≤ 750 (2)
Also, x and y > 0
The profit is given by the function:
Profit = 100x + 110y
Graphing equation 1 and equation 2 and solving, we get the points:
(10, 20)
Hence the maximum profit is at:
Max profit = 100(10) + 110(20) = $3200
If there are 6 friends and half as many food bars as friends, then each friend would get half a food bar. How that each of the 3 food bars are split in half, there is 6 pieces for the 6 friends! :)
Answer:
B. y = 
Step-by-step explanation:
I. Given x = 15 and y = 4
4 = 
4 = 2+2
4 = 4 true
II. Give x = 0 and y = 2
2 = 
2 = 0 + 2
2 = 2 true
III. Given x = -15 and y = 0
0 = 
0 = -2 + 2
0 = 0 true
Good luck.
Remember,
To subtract 2/3-1/2 you have to make them equivalent
2/3×2-1/2×3 = 4/6 - 3/6=
1/6
