When you're adding fractions with two different denominators, the best thing to do is to find a common denominator;
In this case, 4 and 8 are both multiples of 8, and therefore, you've got to double the first fraction.
Doubling the first fraction gives you 2/8 and 3/8. You've then got to add these together, and this gives you 5/8 (as you only add the numerators)
As you're looking for what is left, you have to do 8/8- 5/8 (once again, only subtracting the numerators)
8/8- 5/8= 3/8
Therefore, 3/8 of the muffins are left.
Hope this helps :)

The value of the argument to function g is immaterial to its result. g(x) is 2 for any value of x.
The total sales of Walter is $11468.75
<u>Solution:</u>
Given that, Walter got a pay check for $367 this week.
He makes 3.2% commission on total sales,
We have to find what were his total sales?
