Answer:
B. Multiply (60 − 2x) and (2 + 0.25x) to create the equation y = -0.5x2 + 11x + 120
Step-by-step explanation:
x is the number of price increases of 0.25 each, so (2 + 0.25x) will be the price after x increases.
2 cups remain unsold for every increase in price, so for x increases, 2x cups remain unsold. Then the number sold is (60 -2x).
Revenue is the product of price and quantity sold, so is ...
... revenue = (60 -2x)(2 +0.25x) . . . . . . matches selections A or B
The product of these binomials is ...
... 60·2 +60·0.25x -2x·2 -2x·0.25x
... = -0.5x² +11x +120 . . . . . . . . . . . . . . . . matches selection B
2 -8 and -13 is the answer
Answer:
The equation of the line is y = 2x + 6
<span><span><span>Divide that by the <span>divisor, </span>ignoring the remainder!
Put the whole number result above the line (part of the answer)
</span><span>Multiply that whole number result by the divisor.
Put that below what you just worked on.
