The expressions 100×10 and the more complicated
(100 - 4a)(10 + a)
are calculating annual (expected) revenue. In 100×10 the 100 is the number of decks and the 10 is the price per deck. In (100 - 4a)(10 + a) the 100-4a is the number of decks and the 10+a is the price per deck. So a must be the amount the price increases.
Answer: amount of price increase, last choice
Answer: 9
Step-by-step explanation:
4 + 9 x 2/3 - 1
4 + 18/3 - 1
4 + 6 - 1
10 - 1
9
The answer is 21.5 because 7-3 is 4 so 43 divided 4 is 10.75 so 10.75 times 2 is 21.5
a
x 0.5x + 10 y
0 0.5(0) +10 = 10 (0,10) the y intercept
1 0.5(1) + 10 = 10.5 (1, 10.5)
4 0.5(4) + 10 = 12 (4, 12)
5 0.5(5) + 10 = 12.5 (5, 12.5)
6 0.5(6) + 10 = 13 (6, 13)
b

c
Since they add ten for each call before they multiple miles it is not proportional.
d.
No because the graph shows negative numbers and presumably the company can't charge you if they don't drive there.
1/4 divided by 2 is the answer
