If 120% of a is equal to 80% of b, then what is the value of a+b in terms of a and b?

Answer

As per the statement:

If 120% of a is equal to 80% of b.

"120% of a" means

"80% of b" means

then;

Multiply both sides by 100 we get;

Divide both sides by 80 we have;

Simplify:

       .....[1]

or

   ......[2]

We have to find the value of a+b in terms of a and b:

Substitute the values of [1] we have;

Combine like terms;

Now, find the value of a+b in terms of b;

Substitute equation [2] we have;

Combine like terms;

Therefore, the value of a+b in terms of a and b are;

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
