Suppose you went to a carnival. the price to get in was $4, and you paid $0.50 to get on each ride. if you went to the carnival and rode 7 rides, how much did you spend?

a. $11.50
b. $7.50
c. $9
d. $3.50

i did the work two different ways and eliminated a and d. but i cannot decide which answer out of b and c would be correct

Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Price to enter the carnival = $4

Cost of per ride = $0.50

Since , Number of rides = 7

So, Total amount he will spend is given by

Since Option 'C' is to be eliminate as $9 cant be possible if we take $9 as our answer,

then first we subtract $4 from $5 to get the cost of rides

i.e. 9-4=$5

Now, number of rides will be

which is wrong as we have given that he rode only 7 rides , So, Option 'C' is not correct.

Hence, Option 'B' is correct.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
