Multiply the amount of book Robin read by 1/2.
3/4 x 1/2 = 3/8
Mark read 3/8 of the book.
Answer:
The variables x and y represents the input variable and y represents the output variable.
Step-by-step explanation:
Consider the provided information.
When the bivariate data are the result of two quantitative variables, it is customary to express the data mathematically as ordered pairs (
x,
y),
In mathematics or algebra x is the input variable or we can say that the independent variable.
y is the output variable or we can say that the dependent variable.
Therefore, the variables x and y represents the input variable and y represents the output variable.
Another way to think about this is that $12590 is 80% of the original price. The original was 100%, but this price is 20% off so 100%−20%=80% . The way I like to think is that since I know 12590 is 80%, I can find how much 1% is by dividing 12590 by 80. 12590÷80=157.375.
