Suppose that the population of NYC is 10,000,000, and there're average of 3 people per household
= 3.3 million HHs
and 1 in 10 HHs has a piano
= 330,000 pianos
on average, a piano is tuned once a year
= 330,000 tuning per year
= 6,000 tunings per week
suppose a piano tuner works 5 days a week and handling 5 pianos a day. That will be 25 pianos a week
hence, you need 6,000/25 = 240 tuners
hope this helps
The cost of turkey sandwiches is $3 and chef salads costs $2.
Two equations can be derived from this question:
12t + 44s = 124 equation 1
12t + 58s = 152 equation 2
Where:
t = turkey sandwiches
s = chef salads
In order to determine the value of s, the following steps would be taken:
Subtract equation 1 from 2
14s = 28
Divide both sides of the equation by 14
s = $2
Substitute for s in equation 1
12t + 44(2) = 124
12t = 88 = 124
12t = 124 - 88
12t = 36
t = 3

Answer:
a) How many full packages will be used to ship the jeans?
41 packages
b) How many jeans are left over?
24 Jeans
Step-by-step explanation:
We are told that a manufacturer: made 1500 Jeans and is shipping them in packages of 36.
Hence, the number of packages of 36 he can send out to stores is calculated as:
1500÷ 36
= 41.666666667
In whole number packages = 41 packages
Hence, 41 full packages would be used to ship the jeans.
The number of Jeans left behind is
1500 - (41 × 36)
= 1500 - 1476
= 24 Jeans
