<em>Function, variable, total cost, percentage, jeans
</em>
For this case we have a function of the form
, where 
represents the total cost of buying a pair of jeans, considering that they are 20% below the regular price given by the variable x.
So, if the pair of jeans costs x, we look for 20% of x.
x -----------> 100%
? -----------> 20%
Where "?" represents 20% of x. So, we have:
Thus, 0.2x represents the reduction of the total cost of the pair of jeans
Then, the function that gives the total cost of the pair of jeans, with a reduction of 20% is:
Answer:
Option C
Answer:
60 boys are in the grade.
Step-by-step explanation: Since there are 150 students, we can divide that number by the combined ratio, which in this case is 5. Dividing 150 by 5 would yield 30 students. We can use this information to multiply the given number of boys in the ratio by 30, which would produce 60.
8 is 7
9 is 0.666666666667
0.076 but if you need to round its 0.08
