Question

How do I write an algebraic equation for this word problem?

at a pizza eating contest Mike ate 4 more slices than twice as many slices as the runner-up. If Mike ate 11 slices then how many slices did the runner-up eat?

Answer 1

Hi.

Please note that I haven't done much algebra.

4 more = 4 +

Twice as many than the runner up means 2 times the amount they ate (a variable) = 2n

So far we have 4 + 2n

Since it's an equation, we are going to know what it equals. In the problem, we find out that it's 11. So the equation looks like this:

4 + 2n = 11

If this didn't work out, please let me know.

I believe n = 3.5
