Mark gets a new phone plan that is 30% more expensive than his old plan. If his old plan was $150 a month how much does his new plan cost?
Let's be accurate as possible and think first.
195
His new plan is 150 *.

3 = $45 more expensive than his old plan.

So his new plan is 150 + 45 = $195.

.

Thus, the answer is 195
