At a cafeteria, Mary orders two pieces of toast and a bagel, which comes out to $3.15. Gary orders a bagel and a muffin, which comes out to $3.50. Larry orders a piece of toast, two bagels, and three muffins, which comes out to $8.15. How many cents does one bagel cost?
One Bagel costs 275 Cents
t=3.15-b ( b+m=3.5 which means two more muffins means its an extra 1.5 dollars so one muffin would be .75)
3.15-b+2b+3m=8.15 = b+3m=5
b=2.25 dollars which equals to 225 cents
