Answer:
The price of each meal cost before tax is $ 6.367
Step-by-step explanation:
Given as :
The total price of three meals = $ 20.25
The sales tax included in the total price = 6 %
So, Let the cost of meal before sales tax = x
Or, x + 6 % of x = $ 20.25
or, x + 0.06 x = $ 20.25
Or, 1.06 x = $ 20.25
∴ x =
I.e x = $ 19.10
Or, price of three meals before tax = $ 19.10
so, The price of each meal = = $ 6.367
Hence The price of each meal cost before tax is $ 6.367 answer
Answer:
Total number of cars in the parking lot are 80.
Step-by-step explanation:
Let the number of cars = x and the number of trucks = y
Since, there are 1.5 times many cars than the truck, we get,
Number of cars = 1.5 time number of trucks
i.e.
Also, it is given that when 45 cars were added in the lot, 12 trucks left the parking lot.
So, we get,
Number of cars + 45 = Number of trucks - 12
i.e.
Finally, there are 17 cars more than the trucks.
We have the required equation,
i.e.
i.e.
i.e.
i.e. x= 80
Thus, the total number of cars in the parking lot are 80.
