Answer:
D. The McCarter's must make more than 10 visits to the pool for the pass to be a better deal.
Step-by-step explanation:
First, I chose the option that seemed most likely. Once I chose D, I plugged in the answer to see if it actually worked.
10 x 7.5 =75 dollars + 50 (pass fee) = 125 dollars total.
10 x 12.5= 125 dollars.
Therefore, in order to get a deal off of the seasonal pass, the McCarter's would have to visit the pool more than 10 times. D.
Answer:
Expression: Y = -10/3 X
Y = 10/3
Step-by-step explanation:
If Y varies directly as X, then;
Y∝X
Y = kX
k is the constant of variation
If Y = 10 and X = -3
10 = -3k
k = -10/3
Substitute k = -10/3 into the expression Y = kX
Y = -10/3 X
This gives the required expression
To get the value of Y when X = -1
Recall that Y = kX
Y = -10/3 (-1)
Y = 10/3
Hence the value of Y is 10/3
Answer:
2/3
