Actually Welcome to the Concept of the linear equation in two variables.
So we have to form two equations to solve this.
Let the number of children be 'x' and number of adults be 'y'.
hence, we get as,
x+y = 630 ..... (1)
and also, to their total cost spending, we get as,
1.5x + 2.25y = 1170 ...... (2)
solving (1) and (2) we get as,
Number of children were = 330
and Number of Adults were = 300

Answer:
y = 3/5x + 3
Step-by-step explanation:
y = mx + b
m = slope
slope = rise/run
b = y-intercept
y-intercept = where the line runs through the y-axis.
Answer:
$584.72
Step-by-step explanation:
$262.40+$304.46+$76.04 = $642.90
$642.90 - ($642.90 * 15%) = $546.47
$546.47 + ($546.47 * 7%) = $584.72
I have attached a screenshot for the complete question.
Answer:
A. g is the dependent variable
Explanation:
The given equation is:
g = 748 u
We can see that in this equation, we are converting the gallons into units.
Let's check each variable:
u depends on the usage of each consumer. Therefore, it does not depend on g in this equation. This means that u is the independent variable
g depends on the input u from the consumer. Therefore, g is the dependent variable in this equation.
Hope this helps :)
