Answer: In first question answer is -28x+4

In second question required inequality is 3x+100 < 2x-250

Explanation:

1. Since, here the given expression is 4(x+5)-8(2+4x)

= 4x+20-16-32x ( By distributive property)

=-28x +4 ( By operating like terms)

2. Here, let the number is x.

Then according to the given question, three times the number of candy is increased by 100

That is, 3x+100

And, 250 less than the two times of the candy

That is, 2x-250

And, 3x+100>2x-250

Which is the required expression.

Hence she should subtract 250 from 2x not 2x from 250.
