Question

miss patel thinks her class of 20 students will average 95 on a math test. Before she grades the last students test, the class average is 97. What is the lowest possible score on the 20th test for the class to average 95

Answer 1

see below

Explanation:

`\text{Average = total points / total students}`

`95 = (19*97 + \text{x}) / 20`

`1900 = 1843 + \text{x}`

`\text{x} = 57`

`\text{The lowest the last test score can be for the whole class to average a 95 is} \0 \ \bold{57.}`
