Question

Write two different expressions to represent the number that results

when x is increased by 40%.

Answer 1

`x+ 0.4x`

Or

`1.4x`

Explanation:

When x is increased by 40%, then we find 40% of x and add it to x.

`x + (40)/(100) x`

We can simplify this to get;

`x + (4)/(10) x`

This is the same as:

`x + 0.4x`

When we add we obtain:

`1.4x`
