Grace baked 99 muffins. If Grace gives Jennifer 25 muffins, they will both have the same number of muffins.

The question stated \"IF\".

Meaning Grace never gvie Jennifer the 25 muffins.

Unless the question states \"AFTER\", then it will be included.

Hi lynn,
thanks for coming to my rescue.. I had gone for lunch..had a nice phad thai and was lazy to check the forum..

yes you are correct. The if condition is just helping us to find the initial amount of muffins Jeniffer had..

Since this never happed, we will just use 49 pcs of muffins which she initially had to calculate the amount she will receive..

Hope this explanation helps..

Let x years old be the age of his son.

The man's age will be 4x years old.

Four years ago, the son's age is (x-4) years old.

Hence the man's age is 6*(x-4) = (6x-24) years old.

Form an equation with the man's current age and his age 4 years ago.

You should get:

6x-24+4 = 4x

2x-20 = 0

x = 10

The son's age is 10 years old and the man's age is 40 years old.

I don't remember primary three math to be so complicated.
