You must find the unit cost in dollars per gallon for each purchase by dividing the cost by the number of gallons.
Graven: $55.20 for 15 gallons
$55.20/(15 gal) = $3.68/gal
Project: $72.80 for 20 gallons
$72.80/(20 gal) = $3.64/gal
Answer: Project paid less per gallon.
Step-by-step explanation:
Since f(0) = f(5) = f(8) = 0, we have f(x) = Ax(x - 5)(x - 8), where A is a real constant.
We know that f(10) = 17.
=> A(10)(10 - 5)(10 - 8) = 17
=> A(10)(5)(2) = 17
=> 100A = 17, A = 0.17.
Hence the answer is f(x) = 0.17x(x - 5)(x - 8).
Answer:
75
Step-by-step explanation:
22+39+44-180=75°
supplementary addsup to 180
C= total $ cost
n= number of pizzas purchased
x= $ cost per pizza
C= x * n
C= xn
If you know the cost per pizza and the number of pizzas purchased, plug those numbers in the equation above to find the total cost.
EXAMPLE: If each pizza cost $10 and 5 were purchased, the equation would be: C= ($10)(5)= $50 total
ANSWER: C= xn
