Martin spends 35 minutes exercising daily. Two equivalent expressions to find his exercise time in 7 days are '7 * 35' and '(7 * 10) + (7 * 25)'. Thus, Martin exercises for a total of 245 minutes in 7 days.
First, let's determine the total amount of time Martin exercises daily. He lifts weights for 10 minutes and runs on the treadmill for 25 minutes. Thus, the total time he spends exercising each day is 10 minutes (weightlifting) + 25 minutes (treadmill) = 35 minutes.
Two equivalent expressions for Martin's total exercise time in 7 days can be represented as:
In both cases, they lead to the same conclusion. Hence, the total time Martin spends exercising in 7 days is 7*35 =245 minutes.

First, what you would do is multiply 140 and 20%. Which would give you: 28
Then you would multiply 28 by 4 and get 112
Hope this helps!!(:
d. if he pays 120 cents per litre, how much does it cost to drive to and from work each week? Remember to divide your answer by 100 to convert the cost to dollars and cents.
Answer:
(b) 950 km
(c) 90 litres
(d) $108
Step-by-step explanation:
Henry lives 95 km from work.
Number of km from home to work = 95 km
Number of km from work to home = 95 km
One day = 95 + 95 = 190 km
Assuming he works 5 days a week.
1 day = 190 km
5 days = 190 x 5 = 950 km
Assuming he works 5 days a week.
1 day = 18 litres
5 days = 18 x 5 = 90 litres.
Assuming he works 5 days a week.
1 litre = 120 cents
90 litres = 120 x 90 = 10800 cents = $108
