Answer:
3) Note that she has already walked 5 kilometers (5 x 10 = 50) on Saturday. She needs to walk 30 kilometers (30 x 10 = 300) in all to get to her goal.
C) is your answer, for it is the only one that starts on 30 and continues on. Note that an open dot means that it includes the number it is on, while a closed dot means it does not include.
4) First, find the amount of cost for the everything (except for the outfits, as those do not have an amount yet).
273.98 + 7.23 + 7.23 + 7.23 + 42.36 = 338.03
The total cost for the first 2 points is $338.03.
Subtract the total cost from the amount he has.
500 - 338.03 = 161.97
Now, divide the cost of each outfit from the amount he has left.
161.97/78.12 = 2.07 (rounded = 2)
Note that he cannot buy 0.07 of a outfit, so you must round down (you cannot round up either even if you can, for you will be underpaying).
Mr. Trager can buy at most 2 cycling outfits with the remaining money.
