Answer: it would take 3.1 months

Step-by-step explanation:

Let m represent the number of months that that it will take either of the runners to have the same amount of money in their accounts.

Let y represent the total amount that runner 1 saves for m months

Let z represent the total amount that runner 2 saves for m months

The first runner has $112 in savings, received a $45 gift from a friend, and will save $25 each month. This means that the total amount that he will save for m months would be

y = 112 + 45 + 25m

y = 157 + 25m

The second runner has $50 in savings and will save $60 each month. This means that the total amount that he will save for m months would be

z = 50 + 60m

To determine the number of months before the amount in the account of both runners becomes the same, we would equate y to z. It becomes

157 + 25m = 50 + 60m

157 - 50 = 60m - 25m

35m = 107

m = 107/35

m = 3.06

lbvjy [14]

The local gym holds three 45-minute workout sessions and two 30-minute sessions each week. Then the, total number of minutes Judy worked out for the week was 155 minutes.

We are to determine the total number of minutes Judy worked out for the week.

The gym holds three 45-minute workout sessions and two 30-minute sessions each week

So,

We can write,

The total number of minutes the gym holds workout sessions is

3 × 45 + 2 × 30

= 135 + 60

= 195 minutes

Also, from the information,

Judy left 5 minutes early during the 30-minute sessions and 10 minutes early during the 45-minute sessions.

The total number of minutes Judy didn't attend is

= 3 × 10 + 2 × 5

= 30 + 10

= 40 minutes

Then,

The total number of minutes Judy worked out for the week was,

= 195 minutes - 40 minutes

= 155 minutes

Therefore,

The total number of minutes Judy worked out for the week was 155 minutes.
