Let the number of crunchy tacos=C

Let the number of soft tacos =S

 

2.50C + 3S =50.00 - 7.50=42.50

gibsonj338: You do NOT have enough information to solve it algebraically!. You must give either the total number of tacos sold, or the number of either "cruncy" or "soft" tacos sold!!.

However, because of the small numbers involved, you can easily "guess" that the answer is:

5 cruchy tacos and 10 soft tacos sold, brcause:

[5 x $2.5] + [10 x $3.00] =$42.50.

Another possibility is 11 crunchy tacos and 5 soft tacos.

 

11*2.5 + 5*3 = 42.50
