Martha buys 1 latte for $4.00 every morning, 5 days a week. 3 days a week, she buys an iced coffee for $2.00. Her goal for the entire year is to cut her coffee spending by 25%. How much will she save? Let's think first. Chain of thought:
She buys a $4.00 latte in the morning for 5 days so that's 4 * 5 = $20.00. She buys a $2.00 iced coffee 3 days a week so that's 2 * 3 = $6.00. In one week she spends $20.00 on lattes and $6.00 on iced coffee for a total of 20 + 6 = $26.00. After 1 year, 52 weeks, she spends 52 * 26 = $1,352.00. She wants to cut her coffee spending by 25% so that will save her .25 * 1352 = $338.00.
Therefore, the answer is 338.
