Amom bought her kids 3 cartons of milk for 1.25 and 6 doughnuts. the total cost was 6.90. write an equation to determine the cost of a doughnut

well add the cost together then divide it by the number of doughnuts.

So each doughnut should be like 1.40? close to that

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

brainliest? ?

here try this one

3a-24=0
