The local deli charges a fee, f, for delivery. on monday, they delivered two dozen bagels, b, to an office at a total cost of 58. on tuesday, three dozen bagels were delivered at a total cost of $11. which system of equations could be used to find the cost of a dozen bagels?

  (1)

  (2)

Step-by-step explanation:

For this case we can put some notation

Let b= dozen bagels and f=  delivery fee

And for this case we know that "On Monday, they delivered two dozen bagels, b, to an office at a total cost of $8", so then the total taling in count the delivery fee we have this:

And for the other part "On Tuesday, three dozen bagels were delivered at a total cost of $11", we can write the expression like this:

And our system of equations would be:

  (1)

  (2)

If we solve for f from equation (1) we got:

And if w replace this into equation (2) we got:

And solving for f we got:

it goes right
