Answer 1

Given:

At a college, the tuition increased by 10%. Let b be the former cost of tuition.

Use the expression $b + 0.10b$ for the new cost of tuition.

To find:

The equivalent expression by combining like terms.

Solution:

We have,

$b + 0.10b$

On combining the like terms, we get

$b + 0.10b=1.10b$

Therefore, the required equivalent expression is 1.10b.
