Answer:
B
Step-by-step explanation:
C + 3d = 4.10.....multiply by -2
2c + 2d = 4.60
----------------
-2c - 6d = - 8.20 (result of multiplying by -2)
2c + 2d = 4.60
-----------------add
-4d = - 3.60
d = -3.60 / -4
d = 0.90 <==== cost of 1 doughnut
c + 3d = 4.10
c + 3(0.90) = 4.10
c + 2.70 = 4.10
c = 4.10 - 2.70
c = 1.40 <==== cost of 1 coffee
