Question

Trevor and marissa together have 26 t-shirts to sell. If marissa has 6 fewer tshirts that trevor, find hiw many tshirts trevor has. Identify the if-than moves in your solution

Answer 1

Number of t-shirts Trevor have are 16

If Trevor have 16 t-shirts, than Marissa will have 10 t-shirts.

Explanation:

Let, the number of t-shirts Trevor has = x and number of t-shirts Marissa has = y.

Since, they both have total of 26 t-shirts. We get,

`x+y=26`

Moreover, Marissa has 6 t-shirts less than that of Trevor.

So, we have,

`y=x-6`

On solving the system of equations, we get,

`x+y=26` implies
`x+x-6=26` implies
`2x=26+6` i.e. 2x= 32 i.e. x= 16.

So,
`y=x-6` implies
`y=16-6` i.e y= 10.

Hence, the number of t-shirts Trevor and Marissa have are 16 and 10 respectively.

That is, If Trevor have 16 t-shirts, than Marissa will have 10 t-shirts.
