Question

The average score Josie had in 6 subjects is 72 and her average score after 2 additional subjects were added is 74.25. If she scored 80 in the 7th subject, what was her score in the 8th subject correct to the nearest whole number?

Answer 1

Answer:82

Explanation:

a+b+c+d+e+f/6=72

a+b+c+d+e+f=6*72

a+b+c+d+e+f=432

a+b+c+d+e+f+g+h/8=74.25

a+b+c+d+e+f+g+h=594

g=80

h=?

432+80+h=594

512+h=594

h=82
