Question

Colin’s average for three rounds of golf is 94. What is the highest score he can receive for the fourth round to have an average (mean) of 92?

Answer 1

Answer:86

Step-by-step explanation: The lowest score that he could get in the fourth round is 86 in order to have an average of 92. The steps that you would take to calculate this are as follows:

Multiply 92 x 4 = equals the total number of points that he needs to earn in all four rounds

92 x 4 = 368

Next, subtract the total for the first three rounds. Since the average is 94, you will subtract the total of 3 x 94, which equals 282.

Subtract 368 - 282 = 86.

You can then double check your work by adding up the total of the four games and dividing by four for the average. 94+94+94+86=368 368/4=92
