Answer:the cost of each CD for a member is $5.25
Step-by-step explanation:
The membership costs $22 per year, and then a member can buy CDs at a reduced price.
Let x represent the cost of each CD for a member.
Let n represent the number of CDs that each member buys. This means that the total cost of buying n CDs for a member for a year would be
22 + nx
If a member buys 17 CDs in one year, the cost is $111.25. This means that
17x + 22 = 111.25
17x = 111.25 - 22 = 89.25
x = 89.25/175 = 5.25
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
x=5/2
Decimal Form:
x=2.5
Mixed Number Form:
x=2 1/2
Step-by-step explanation:
The amount of gas in her tank after 8 days given the linear equation g = 213 - 1.6d is 200.2 gallons of gas
<h3>Linear equation</h3><h3 />
- Gallons of gas used per day = 1.6 gallons
- Number of days = d
- Quantity of gas = g
The equation
g = 213 - 1.6d
Gas remaining after 8 days
g = 213 - 1.6(8)
= 213 - 12.8
g = 200.2 gallons of gas
