Roger goes to the store to buy some coffee. The normal brand of coffee he buys cost $5 per pound. He had to buy a more expensive brand that cost 20% more since his favorite brand was sold out. He decides to buy a week's worth of coffee and he uses 1 pound of coffee per day. He also decided to buy himself a donut for $2. How much did everything cost?

How much more expensive was the coffee he bought? ** The coffee he bought was 5*.2=$<<5*.2=1>>1 more expensive per pound than what he normally buys
How much did the coffee he bought cost? ** So it cost 5+1=$<<5+1=6>>6 per pound
How many pounds of coffee does he go through in a week? ** He goes through 1*7=<<1*7=7>>7 pounds of coffee a week
How much did the coffee he bought cost? ** So he paid 6*7=$<<6*7=42>>42 on coffee
How much did everything cost? ** That means his total bill was 42+2=$<<42+2=44>>44
