Answer:

the price for each doughnut is $1.05

Step-by-step explanation:

doughnuts = d

cookies = c

2d + 3c = $3.30

5d + 2c = $4.95

to find the answer multiply 2 with the first equation, and multiply -3 with the second equation.

4d + 6c = 3.30

-15d - 6c = -14.85

combine like terms

-11d = -11.55

divide by -11

d = 1.05
