Andrew and ryan spend a total of $44 at a state fair. there is an entrance fee of x dollars per person, and each ride costs $3.50. if they went on the same number of rides, which equation correctly represents this relationship, where n is the number of rides? choose all that apply.
a. x + 7n = 44
b. 2(x + n) = 44
c. 2(x + 3.5n) = 44
d. x + 3.50n = 44
e. 2x + 7n = 44
f. 2x + 3.50n = 44

C. 2(x + 3.5n) = 44

E. 2x + 7n = 44

Step-by-step explanation:

Hi, to answer this question we have to write an equation that represents the situation:

So, the total money spent by the 2 friends is $44. That cost is equal to the price of the entrance fee (x) multiplied by 2 (since they are 2), plus the cost of each ride (3.50) multiplied by the number of rides (n) and also by 2 (since they are 2)

Mathematically speaking:

2(x + 3.5n) = 44

So, the correct options are  

C. 2(x + 3.5n) = 44

E. 2x + 7n = 44 (is equivalent, obtained if we apply distributive property to option C.)

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
