Answer: 1100 grams
Step-by-step explanation:
5kg=5000g
5000g-600g=4400g
4400g/4=1100g
85 x 3 = 255
first 2 test grades were 81 and 86:
81 + 86 = 167
Need to find the 3rd to have exact average 85:
255 - 167 = 88
So her 3rd test needs to make 88 to make average of 85
Double check: 81 + 86 + 88 = 255 = 85 + 85 + 85
