Question

Write two different expressions to represent the number that results when x is increased by 40%.

Answer 1

Answer:

$x+ 0.4x$

Or

$1.4x$

Step-by-step explanation:

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

$x + \frac{40}{100} x$

We can simplify this to get;

$x + \frac{4}{10} x$

This is the same as:

$x + 0.4x$

When we add we obtain:

$1.4x$
