Question

Laura is bowling 5 games. Her first 4 scores were 118, 128, 124, and 98. To end up with an average score of at least 123.2, what is the lowest score Laura will need in the fifth game?

Answer 1

Answer:

148

Step-by-step explanation:

Average = sum of numbers /total numbers

let x = 5th number

123.2 = (118+ 128 + 124,+ 98 + x) / 5

123.2 = (468 + x) / 5

Multiply both sides by 5

616 = 468 + x

x = 148
