It is convenient to let a spreadsheet or graphing calculator do the math for this. Functions can be defined for cost and profit, and evaluated at each of the volumes of interest.
a1) For 200 cars, the Outside location yields the greatest profit
a2) For 300 cars, the City location yields the greatest profit
b) The sites yield the same profit for a volume of 278 cars.
17^2 = 289
23^2 = 529
529 + 289 = 818
√818 = 28.6 inches
Answer:
H
Step-by-step explanation:
In this question, I will assume that the cost refers to the selling price (original price without discount) of the hammer.
Let the cost of each hammer be c.
∴ Cost of 50 hammers= 50c
Cost of 50 hammers= amount paid +discount given
50c= 100 +25
Here, we add the discount given since the actual cost would be $25 more than the total amount the contractor paid.
Since none of the options match our equation above, let's rearrange the equation.
Subtract both sides by 25:
50c -25= 100
Thus, H is the correct option.

297 I think because 45+21=66, then x9= 594 divided by 2 is 297
Cross multiply: 20 * b = 45 * 34
Simplifying: 20 * b = 45 * 34
Multiply 45 * 34: 20b = 1530
Solving: 20b = 1530
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Divide each side by '20': b = 76.5
Simplifying: b = 76.5
