Iwent to my favorite taco stand with some friends. between us we bought 6 tacos and 2 burritos, and i noticed that the ratio of the amount we spent on tacos to the amount we spent on burritos was 7: 4. later we went back and bought 4 tacos and 3 burritos and spent 1 dollar less. how much money did we spend that time?

  $32

Step-by-step explanation:

First, we'll use the given relations to find the costs of a taco and burrito, then we'll compute the bill for the second visit to the taco stand.

Let t represent the cost of a taco, and b represent the cost of a burrito. The first trip to the taco stand resulted in costs that have the relation ...

  (6t)/(2b) = 7/4

Multiplying by 4b, we get ...

  12t = 7b . . . . . [eq1]

On the second trip to the taco stand, the costs have the relation ...

  (4t +3b) = (6t +2b) -1 . . . . . . subtracting 2b+4t from both sides gives ...

  b = 2t - 1 . . . . . [eq2]

__

Substituting the expression for b in [eq2] into [eq1], we get ...

  12t = 7(2t -1)

  0 = 2t -7

  7/2 = t = 3.5

  b = 2t -1 = 6

__

The spending on the second trip was ...

  4t +3b = 4(3.5) +3(6) = 32 . . . . dollars

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
