Answer:
Her actual distance for the trip will be 112.5 miles.
Step-by-step explanation:
You need to analize the information provided in the exercise.
You know that the scale of the map Kelsey is reading is:
And according to the exercise, Kelsey's trip measures 4.5 inches on that map.
Therefore, in order to calculate what will be her actual distance for the trip (Let be 
this distance), you can set up the following proportion:
Finally, you must solve for . Then, you get:
Therefore, her actual distance for the trip will be 112.5 miles
Answer:
a. 7(2g + 20t –3)
b. 14g + 140t – 21
Step-by-step explanation:
a. The first expression 7(2g + 20t – 3)
Stacey and her six friends implies that we have 7 members in the group.
Therefore, the expression above implies that each member of the group has to pay for two rounds of golf and 20 tokens will be discounted $3.00.
The expression (2g + 20t –3) represents the quantity of cost of each friend and this is multiplied by 7 to obtain this first expression, i.e. 7(2g + 20t –3).
b. The second expression 14g + 140t – 21
The simple interpretation of this expression us that deducting $21 from the to total bill which is 14 games of golf plus 140 tokens is equal to the total amount this group spent.
Therefore, this second expression is obtained by simply opening the bracket in the first expression by multiplying 7 by each of the what is in the bracket.
