The total tickets bought is 7 and they spent $202
Each adult ticket costs $34 and each youth ticket costs $22
Let "x" be the number of adult tickets and "y" be the number of youth tickets.
You can calculate the total number of tickets as
And the total amounf of the purchase as the number of adults tickets multiplied by its price (34x) plus the number of youth tickets multiplied by its price (22y)
Now we have an equation system determined and can calculate the values of x and y.
1) Write the first equation in terms of one of the variables, for example in terms of x
Next replace that expression in the second equation and calculate the value of y
Solve the multiplication by applying the distributive propperty of multiplication
Pass 238 to the other side of the equation by applying the inverse operation to both sides of it, i.e. "238" is positive, so you have to subtract it
Divide both sides of the equation by -12 to get the value of y
With this value calculate x as:
They bought 4 adult tickets and 3 youth tickets (Answer B.)
