First you will have to calculate how much the fair admission costs were.
Star spent $43.75 on rides and the admission together.
One ride ticket costs $1.25, so 25 ride tickets cost:
1.25 x 25 = $31,25
The admission costs will then be:
43.75 - 31.25 = $12.50
A normal linear equation goes like this:
y = c · x
x is supposed to be the number of ride tickets. you add the costs of those tickets in front to show how much money it will be.
y = c · 1.25x
Your constant in this case is the admission, it is the same for everyone, $12.50, so your equation will be:
y = 12.5 · 1.25x
Answer:
the first answer
Step-by-step explanation:
1/8 of the absolute value is 1/8 positive
anything from the absolute value is positive because absolute value is the value of how far away the number is from zero.
Answer: 168 adult tickets were sold.
Step-by-step explanation:
We know that we can find the number of adult and student tickets sold, with this equation:
Since 82 students attended, we can substitute into the equation and solve for "a", in order to calculate the amount of adult tickets sold.
Then, "a" is:
Subtract the y values to one side then the numbers to the other so as x values to one side then the numbers to the other
Answer:
Roasted Steak RS=14.47
Grilled Salmon GS= 25.21
Step-by-step explanation:
It's a 2 equation system as follows
E1-> 17RS+14GS=598.95
E2-> 28RS+7GS=581.64
We assume the system has only one solution and apply the following calculation to create a single equation
E3 -> 2x E2 -E1
That way the only incognit will be RS
(28x2 - 17) RS + (7x2 - 14) GS = 581,64x2- 598,95
39RS= 564,33
We solve for RS and then use E1 to solve for GS and E2 to check the answers
