Brenden runs six times a week for thirty minutes and lifts three times a week for twenty minutes. Write a mathematical expression for the number of hours Brenden works out in a week.

Step-by-step explanation:

Let the number of hours for running be x

And the number of hours for lifts be y

Let the total hours for work out be H

Given that

x= 30 min* 6= 180 min =3 hours

y= 20 min *6 =120 min=  2  hours

H= 30(6)+ 20(6)

H= 180+120

H= 3+2

H= 5 hours of work out for the  week

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.

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.
