Answer:
67%
Step-by-step explanation:
Given : A department store buys 300 shirts at a cost of $1800 .
Then By unitary method , the cost of one shirt = Cost of 300 shirts divided by 300
= $1800 ÷ 300 = $6
i.e. cost of one shirt = $6
Also, Selling price of one shirt = $10
Price mark up = Selling price - Cost price
= $10-$6 = $4
The percent mark up=
(rounded to the nearest percent)
Hence, the percent markup = 67%
Answer:
The rate at which the distance between the two cars is increasing is 30 mi/h
Step-by-step explanation:
Given;
speed of the first car, v₁ = 24 mi/h
speed of the second car, v₂ = 18 mi/h
Two hours later, the position of the cars is calculated as;
position of the first car, d₁ = 24 mi/h x 2 h = 48 mi
position of the second car, d₂ = 18 mi/h x 2 h = 36 mi
The displacement of the two car is calculated as;
displacement, d² = 48² + 36²
d² = 3600
d = √3600
d = 60 mi
The rate at which this displacement is changing = (60 mi) / (2h)
= 30 mi/h
