Ned opens a left-handed store. He sells left-handed mice. They cost 30% more than normal mice. He sells 25 a day and his store is open every day except Sunday, Thursday, and Friday. If normal mice cost $120 how much money does he make a week?
Step-by-step reasoning process below:
15600
The left - hand mice cost 120 *.

3 = $36 more than right - handed ones.

So they cost 120 + 36 = $156.

So he makes 156 * 25 = $3900 a day.

The store is open 7 - 3 = 4 days a week.

So in a week, he makes 3900 * 4 = $15,600.

.

Therefore, the answer is 15600
