Question

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 please help?!?!?!

Answer 1

Answer: 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

$4+0.50\times 7\\\\=4+3.5\\\\=\ 7.50$

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

$\frac{5}{0.5}=10$

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

Hence, Option 'B' is correct.

Answer 2

If it was to get in and rides it would be B. 7.50 but if it is only rides then it is D. 3.50
