Question

Luckily ,those shoes are ,so I can buy them

Answer 1

Answer:-

Luckily ,those shoes are ____________ ,so I can buy them

Luckily ,those shoes are cheap enough ,so I can buy them

how?

lets try adding the given options in the question

1. Luckily ,those shoes are to cheap ,so I can buy them
2. Luckily ,those shoes are enough cheap ,so I can buy them
3. Luckily ,those shoes are cheap enough ,so I can buy them
4. Luckily ,those shoes are cheap too, so I can buy them

in case 1 too cheap cannot be the right answer as in the question it is specified that he can buy them, so it should be cheap or just right

in case 2 enough cheap wont make sense either as 'enough cheap' needs to be reframed to make the sentence right.

in case 4 cheap too does not make much of a sense either.

in case 3 cheap enough makes sense as in the question we are referring that the shoes are at a affordable price, so cheap enough is the right answer.

hope it helps you!
