Answer:
f = 4d -400
Step-by-step explanation:
First, let's make some variables.
f = size of Falls Lake
d = size of Lake Drummond
d = (1/4)*f + 100
We can now rearrange the equation to find the size of Falls Lake.
d - 100 = (1/4)*f
4d - 400 = f
f = 4d - 400
155;
rounding to the nearest whole number basically means rounding the decimals so they disappear e.g. 11.5 would round up to 12 because 5+ rounds upwards and below 4 rounds down so say it was 15.34 it would round down so it would be 15.
I hope this helps ;)
