X= # of adults
y= # of children
1326= 6x + 4y
289= x + y
We are going to do substitution.
x = 289-y
1326= 6(289-y) + 4y
1326= 1734 -6y + 4y
1326= 1734 + -2y
-408= -2y
204 = y
Since we now have a value for y, we should plug that back into the equation we got the x value from to find the actual numerical value of x.
289= x + y
289= x + 204
85= x
In conclusion, 85 adults and 204 adults went to the swimming pool.
Answer: $8.60
Step-by-step explanation:
Let the price of a bread = x
Let the price of a tarts = x - 1
If 3 times the price of a loaf of bread is $29.5 more than half of the price of a box of tarts. This can be represented as:
3 × x = 1/2 × (1 - x) + 29.5
3x = 0.5 - 0.5x + 29.5
3x + 0.5x = 29.5 + 0.5
3.5x = 30
x = 30/3.5
x = 8.6
