Answer:
There is a formula for this:
[Worker 1 Time * Worker 2 Time] / [Worker 1 Time + Worker 2 Time]
[2 * 1.5] / [2 + 1.5] = 3.0 / 3.5
= 0.8571428571 Hours =
51.43 minutes
Both Jenna and Juan are INCORRECT.
Step-by-step explanation:
The product of 670 and 4 is 2,680
For the Community Gym:
Membership Charge = $50
Monthly fee = $55
So for the 1st month total charge = $(50 +55)
= $105
For each month the member pays $55
So after the 2nd month total payment = $(105 + 55)
= $160
After 3rd month total payment = $(160 + 55)
= $215
After 4th month total payment = $(215 + 55)
= $270
After 5th month total payment = $(270 + 55)
= $325
After 6th month total payment = $(325 + 55)
= $380
Now for the Workout Gym:
Membership Charge = $200
Monthly Charge = $45
So for the 1st month the member pays = $(200 + 45)
= $245
For the 2nd month total payment = $( 245 +45)
= $290
For the 3rd month total payment = $(290 + 45)
= $335
For the 4th month total payment = $(335 + 45)
= $ 380
So the 6th month payment in the Community Gym is the same as the 4th month payment in the Workout Gym. The amount will be $380.
