Jamian bought a total of 45 bagels and donuts for a morning meeting. He paid a total of $44.00. Each donut cost $0.70 and each bagel cost $1.20. The system of equations 1.20b +0.70d = 44.00 models this situation, where b is the number of bagels and d is the number of donuts. How many of each did Jamian buy?
