Answer:
g is the independent variable.
u is the independent variable.
Step-by-step explanation:
According to the question, the data mentioned is as follows
Equation g = 748u
where,
g = the total number of gallons of water used
And, u = the number of units.
As we've seen, Consumers are using the number of units of water.
The volume of water units does not depend on the total quantity of gallons of water that is being used.
So, the number of units i.e u represents an independent variable.
hence,
The value of the total quantity of gallons is entirely dependent on the number of units used, and the g represents the dependent variable
Therefore,
The third and fourth option is correct
The amount paid by sam will be 11526.75k for the meal.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that:-
Sam pays 512 .75k less than the amount rob pays for his meal .ridwan pays three times the amount rob pays for his meal. if the total amount paid by them is 47,645.25k.
We will form an expression from the data given above in the question.
Amount paid by Sam = ( r - 512.75 )
Amount paid by rob = r
( r - 512.75 ) + 3r = 47645.25
( r + 3r ) = 47645.25 + 512.75
4r = 48158
r = 12039.5
The amount paid by sam will be calculated as:-
S = r - 512.75
S = 12039.5 - 512.75
S = 11526.75
Therefore the amount paid by sam will be 11526.75k for the meal.
