John used to buy 4 coffees a day for $2 each. They raised the price by 50% so he cut the number of coffees he drinks in half. How much money does he save per day compared to what he used to spend?
Use reasoning to answer the following question.
2
He now buys 4 / 2 = 2 coffees.

The new price is 2 *.

5 = $1 more than the old price.

So he now pays 2 + 1 = $3 per coffee.

So he spends 3 * 2 = $6.

He used to spend 4 * 2 = $8.

So he saves 8 - 6 = $2 per day.

.

Final answer: 2
