On a test, the highest grade was 40.5 points higher then the lowest grade. The sum of the two grades was 138. Find the lowest grade.

Answers

Answer 1

Answer:

48.75

Step-by-step explanation:

call highest H and lowest L

H = L + 40.5

sum of them = 138

H + L = 138

(L + 40.5) + L = 138

2L + 40.5 = 138

2L = 138 - 40.5 = 97.5

L = 48.75
