Billie and toni are driving from chicago to phoenix. the first day they drove 420 miles. they want to drive at 65 miles per hour for the rest of their trip. a. write an algebraic expression to represent the situation. b. if they drive 8 hours a day for the next two days, how far have they traveled by the end of the third day?

A. We are given that they already drove 420 miles and an additional of 65 miles per hour. Therefore distance covered is:

d = 420 + 65 t

where d is distance and t is time

B. If they drove 8 hours per day for 2 days, then total time is t = 16 hours, hence:

d = 420 + 65 * 16

d = 1460 miles

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

3; 9 is 8 to -4
