"If 3 is added to twice a number, the result is 17. Find the number"
Let's call the number we want to find.
Twice the number is equal to
So, if we add 3 to 2x, we get
And we know that this is equal to 17:
Now we can solve the equation to find x: first, we subtract 3 from both sides
Now we divide both sides by 2:
Answer:
1 $16.50
2 $28.50
3 $40.50
$4.50 + $12c
$100.50
Step-by-step explanation:
Please find attached the complete question
Total cost in dollars = fixed cost + (variable cost x number of CDs bought)
fixed cost = $4.50
variable cost = $12
number of cds bought = c
total cost in dollars = $4.50 + $12c
total cost in dollars when 1 cd is bought = $4.50 + $12(1) = $16.50
total cost in dollars when 2 cds are bought = $4.50 + $12(2) = $28.50
total cost in dollars when 3 cds are bought = $4.50 + $12(3) = $40.50
total cost in dollars when 8 cds are bought = $4.50 + $12(8) = $100.50
