A gas pump machine rejects 12% of
credit card transactions. If this is twice the normal rejection rate for a
normal gas pump, how many out of 500 credit card transactions would a
normal gas pump machine reject?
IDK but can someone help me
A gas pump machine rejects 10% of credit card transactions. If this is twice the normal rejection rate for a normal gas pump, how many out of 650 credit cards transactions would a normal gas pump machine reject?
Its 30
To find out how many credit card transactions a normal gas pump machine would reject out of 500, we can start by determining the normal rejection rate.
Since the given rejection rate of the machine in question is twice the normal rate, we can calculate the normal rejection rate by dividing 12% by 2.
Normal rejection rate = 12% / 2 = 6%
Now, we can calculate the number of rejected transactions by multiplying the normal rejection rate (6%) by the total number of credit card transactions (500).
Rejected transactions = (6% / 100) * 500
Rejected transactions = 0.06 * 500
Rejected transactions = 30
Therefore, a normal gas pump machine would reject 30 out of 500 credit card transactions.
