Answer:
option C
Step-by-step explanation:
given,
Beginning inventory 10 units @ $10 per unit
First purchase 35 units @ $11 per unit
Second purchase 40 units @ $12 per unit
Third purchase 15 units @ $13 per unit
first sale = 20 units
second sale = 35 units
now,
unit left after first sale = 35 - 20 = 15 units @ $11 per unit
unit left after second sale = 40 - 35 = 5 @ $12 per unit
third purchase = 15 units @ $13 per unit
inventory = 10 units @ $10 per unit + 15 units @ $11 per unit + 5 @ $12 per unit + 15 units @ $13 per unit
= 100 + 165 + 60 + 195
= $ 520
hence, the correct answer is option C
The cost of one adult ticket is $7.5 and one child ticket is $3.5
Julia will pay $48 for 5 adult tickets and 3 child tickets.
Step-by-step explanation:
Let,
Cost of one adult ticket = x
Cost of one child ticket = y
According to given statement;
3x+5y=40 Eqn 1
x+5y=25 Eqn 2
Subtracting Eqn 2 from Eqn 1

Dividing both sides by 2

Putting x=2.5 in Eqn 1

Dividing both sides by 5

The cost of one adult ticket is $7.5 and one child ticket is $3.5
5 adult tickets = 5*7.5 = $37.5
3 child tickets = 3*3.5 = $10.5
Total = 37.5+10.5 =$48
Julia will pay $48 for 5 adult tickets and 3 child tickets.
