To find the ratio divide the number of games won by the number of games lost
so
substitute the values
Simplify
Answer:
4
Step-by-step explanation:
If two variables are proportional then
...(i)
where, k is constant of proportionality.
The given equation is
...(ii)
where,
s = number of cups of seltzer.
c = cups of cranberry juice.
On comparing (i) and (ii), we get
Independent variable:
Dependent variable:
Constant of proportionality:
Therefore, the constant of proportionality is 4.
The answer is:
Tito needs a total of $6500 in sales if he want to receive $710 a week.
The equation is:
From the statement we know that his salary is $450 plus a 4% commission on the total amount of all sales he makes.
So, we can write the following equation to determine the total sales in a week if he wants to make a total of $710.
Remember, if we are working with percents, we need to change it to real numbers in order to perform the calculations, we can do it by dividing the percent value into 100.
We have:
Now, if he wants to make a total of $710, we have:
We have that Tito needs a total of $6500 in sales if he want to receive $710 a week.
Have a nice day!
