Answer: 131 miles; 21 x 3 = 63 + 17 x 4 = 68. 63 + 68 = 131 miles
Hence, the cyclist ride in [tex]7[/tex] hour is [tex]131[/tex]miles.
What is the speed?
The magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.
Here given that,
A cyclist rode at a constant speed of [tex]21[/tex]mph for [tex]3[/tex] hours. Then she decreased her rate of speed to [tex]17[/tex] mph for [tex]4[/tex] hours.
[tex]21[/tex] x [tex]3[/tex] [tex]=63 + 17 (4)[/tex]
[tex]= 131[/tex] miles
Hence, the cyclist ride in [tex]7[/tex] hour is [tex]131[/tex]miles.

You are buying cupcakes for a school party. They are in a package of 6 for $8.50. You have budgeted no more than $40 to spend. If cost of the cupcakes is a function of the number of packages purchased, what is the largest element of the domain in this situation?
Answer: Largest element in the domain is 4
The largest number of packages you can buy is 4
======================================================
Explanation:
1 package costs 8.50*1 = 8.50 dollars
2 packages cost 8.50*2 = 17 dollars
3 packages cost 8.50*3 = 25.50 dollars
and so on. In general
x packages cost 8.50*x = 8.50x dollars
where x is a place holder for a positive whole number (1,2,3,...)
The total amount spent is 8.50x and the budget is $40
This means,
[tex]8.50x \le 40\\\\x \le \frac{40}{8.50}\\\\x \le 4.70588\\\\x \le 4\\\\[/tex]
We round down regardless of how close we are to 5.
If x = 4, then 8.50*x = 8.50*4 = 34
While if x = 5, then 8.50*x = 8.50*5 = 42.5
So we see we go over budget if we buy x = 5 packages.
This makes x = 4 the largest in the domain.
Recall the domain is the set of allowed x inputs. In this case, x is a positive whole number (since we can't buy half a package for instance).
