John went to the bakery and bought

several dozen donuts and several

dozen bagels. The donuts cost $9

per dozen and the bagels were $8

per dozen. If he spent a total of

$101 for 12 dozen items, how many

donuts did he buy?

5 dozen Donuts

7 dozen bagels

Step-by-step explanation:

5 * 9 = 45

7 * 8 = 56

56 + 45 = 101

Answer: He bought 5 dozen donuts

Step-by-step explanation:

d + b = 12 where d is the number of donuts and b is the number of bagels.

9d + 8b = 101 now solve the two equations using the elimination method

-9d - 9b = -108

9d + 8b = 101

-1b = - 7

b = 7

9d + 8 (7) = 101

9d + 57 = 101

9d = 45

d = 5
