If you make both equations equal each other, you can then solve the system of equations.
Okay, we know that the expenses for the day is 210.
Knowing this, and the price of the taco, we write the inequality:
3.25t > 210
t = number of tacos
Now divide both sides by 3.25:
t > 64.62 (rounded)
Because a taco stand can't sell a fraction of a taco, we know that the taco stand has to sell more than 65 tacos for a profit.
Answer:
another number =27
Step-by-step explanation:
Let X stand for the larger number. The smaller number is therefore X - 13. We can now write the sum of the two numbers as:
X + (X - 13) = 4
X + X - 13 = 41
Gather the X’s and rewrite as,
2X - 13 = 41
Add 13 to both sides to get
2X = 54
Divide both sides by 2 to solve for X,
X = 27
