To justify the yearly membership, you want to pay at least the same amount as a no-membership purchase, otherwise you would be losing money by purchasing a yearly membership. So set the no-membership cost equal to the yearly membership cost and solve.
no-membership costs $2 per day for swimming and $5 per day for aerobic, in other words, $7 per day. So if we let d = number of days, our cost can be calculated by "7d"
a yearly membership costs $200 plus $3 per day, or in other words, "200 + 3d"
Set them equal to each other and solve:
7d = 200 + 3d
4d = 200
d = 50
So you would need to attend the classes for at least 50 days to justify a yearly membership. I hope that helps!
Answer:
75
Step-by-step explanation:
85% have been hired, so 15%, or 15 out of 100 remain to be hired. The capacity is 500 = 5×100, so 5×15 = 75 employees need to be hired.
Answer:
75
Step-by-step explanation:
total number of employees to be staffed= 500
percentage of employees already staffed= 85%
therefore % of employees to be staffed= 100-85= 15%
number of employees to be staffed= 15% of 500
=[tex]\frac{15}{100}\times500[\tex]
=75
75 employees are needed to be hired for fully staffed
