Answer:
11.1
C is the correct option.
Step-by-step explanation:
We have been given the equation and we have to evaluate this expression for
In order to find the same, we can substitute x = -7.2 in the expression
Now, we know the rule (-)(-)=+
On adding, the numbers, we get
Hence, the value of the expression at x = -7.2 is 11.1
C is the correct option.

Question:
Veronica is choosing between two health clubs. after how many months will the total cost for each health club be the same? yoga studio a: membership: $24.00 monthly fee: 21.50. yoga studio b: membership: $41.00 monthly fee: $17.25
Answer:
It takes 4 years for the total cost of each club to become equal
Step-by-step explanation:
Given:
For yoga studio A:
membership: $24.00
monthly fee: 21.50.
For yoga studio B:
membership: $41.00
monthly fee: $17.25
To Find:
Number of months after which the total cost for each health club be the same = ?
Solution:
Let x be the number of months of membership, and y be equal the total cost.
For Yoga club A
y = 21.50 x + 24
For Yoga club B
y = 17.25 x + 41.00
we know that the prices, y , would be equal, we can set the two equations equal to each other.
21.50 x + 24 =17.25 x+ 41.00
Grouping the like terms,
21.50x - 17.25 x= 41.00 - 24
4.25x=17
x=
x = 4
