Bud makes homemade macaroni and cheese once a week.  The pasta costs $1.00 a box, and he spends $3.00 on cheddar cheese and twice that amount for the gruyere cheese.  How much money does Bud spend on making macaroni and cheese in one year?
The gruyere cheese is twice the cost of the $3.00 cheddar cheese so it costs 2*3 = $<<2*3=6.00>>6.00
The pasta costs $1.00, the cheddar cheese costs $3.00 and the gruyere cheese is $6.00 for a total of 1+3+6 = $<<1+3+6=10.00>>10.00
There are 52 weeks in a year and he makes this dish once a week so it will cost him 52*10 = $<<52*10=520.00>>520.00 in one year
