You are right on the answer
Let the time that you caught up with your friend be t, then
8.5 - 3.4t = 8 - 3t
3.4t - 3t = 8.5 - 8
0.4t = 0.5
t = 0.5/0.4 = 1.25
therefore, you will catch up with your friend after 1.25 hours.
b.) time it will take you to cross the finnish line = 8.5/3.4 = 2.5 hours
After 2.5 hours, distance covered by your friend = 3 x 2.5 = 7.5 miles
Therefore, when you cross the finish line, you are 8 - 7.5 = 0.5 miles ahead of your friend.
<u>Answer:</u>
The correct answer option is b. Darius will get the better deal buying one 16 ounce bottle.
<u>Step-by-step explanation:</u>
We know that a 16 ounce bottle of the salad dressing is for $3.36 while a 10 ounce bottle is priced at $2.30.
Darius has a coupon for 40 cents off if he buys two 10 ounce bottles. We are to determine what is the better buy.
Price of one 16 ounce bottle = $3.36
Price of two 10 ounce bottles = (2.30 × 2) - 0.4 = $4.2
Therefore, Darius will get the better deal buying one 16 ounce bottle.
