Answer:
Step-by-step explanation:
Well... this is a typical question about system of equation ...
You have to find two equations to build the system and then, choose the best method for you.
First of all, let’s call deluxe taco as x and veg taco as y.
Kenya orders 50 tacos:
X+y=50 (this is our 1st eq.)
The second one will be just like that:
“X cost 2.95 and y cost 2.25. The total price before the tax is 137”
2.95 . X + 2.25 . Y = 137
Building the system:
X+y=50
2.95x + 2.25y = 137
Well... for this system, I prefer to choose the substituition method
On the first equation, I rewrite just like that X=50-y
On the second equation:
2.95 (50-y) + 2.25y = 137
147.5 - 2.95y + 2.25y = 137
-0.7y = -10.5
Y = 15
X+y=50
X+15=50
X=35
