2 pairs of goggles and 3 swimming caps cost $60.30.3 pairs of goggles and 5 swimming caps cost $95.20.
Find the cost of a swimming cap.

Answers

Answer 1
Answer:
2g + 3s = 60.3
3g + 5s = 95.2
If you look at the first formula we could write it as
g = (60.3)/(2) - (3s)/(2)
And if you write this instead of the g in the second equation you get
3((60.3)/(2) - (3s)/(2) ) + 5s = 95.2
(180.9)/(2) - (9s)/(2) + 5s = 95.2
5s - 4.5s = 95.2 - 90.45
0.5s = 4.75
s = (4.75)/(0.5)
s = 9.5

Swimming cap costs $9.5
Answer 2
Answer:

Try to divide 95.20 by 1. In this question you are looking for the unit rate so you have to use 1.

David recorded his finishing time, in seconds, for each time he ran the 100 m race during one track season. What was the median of his finishing times?11. 9 11.9 12.0 12.1 12.1 12.2 12.3 12.4 12.4

Answers

The median is 12.1 because it is the center number in the sequence. This only applies if the numbers are in order from least to greatest, and also if there are a even number of numbers in the sequence you must take the average of the two center ones because there is no center one.
