Answer:
Elena won the race.
Step-by-step explanation:
If you calculate it, Lin runs a mile every 9 minutes.
9 times 7.5= 67.5 which is 1 hour, 7 minutes and 30 seconds. While it took only an hour for Elena to run 7.5 miles.
Which means Elena's speed was faster and got her to the finish line first.
$2.39 * 2 (jars of peanut butter) = $ 4.78. $4.78 - $1 (discount because of the coupon when buying 2 jars of peanut butter) is equal to $3.78. Therefore, the final price of the two jars is $ 3.78.
To simply put -
($2.39 * 2) - $1 = $3.78
