Chester, the dog, loves to eat treats. He has eaten twice as many today as yesterday. He has eaten a total of 15 dog treats in both days.

-write the equation-

Answer 1

The equations are:

`T = 2Y` and
`T + 2Y = 15`

Explanation:

Given

Represent bones eaten Today with T and yesterday with Y

Required

Write the equation

In the first statement, we have that:

`T = 2Y`

Reading further; In the second statement

`T + 2Y = 15`

Hence, the equations are:

`T = 2Y` and
`T + 2Y = 15`

Solving further:

Substitute 2Y for T in the second equation

`2Y + 2Y = 15`

`4Y = 15`

Divide both sides by 4

`Y = (15)/(4)`

`Y = 3.75`

Recall that

`T = 2Y`

`T= 2 * 3.75`

`T= 7.5`
