The answer is 300 is 10 times as much as 3000
Proof:
5x-21=24
5x=24+21
5x=45
x=9
Hope this can help.
The total cost if the cafeteria makes the pizza is:
cost = 44.20 + 6.25 p
where p is the number of pizza
while the cost if it is ready made is:
cost (ready made) = 14.50 p
Equating the two to find for x:
44.20 + 6.25 p <
14.50 p
p > 5.35
So it is cheaper when 6 pizzas or more is made
Answer:
The volume of paint that covers the whole car is gallons or one and a quarter gallons.
Step-by-step explanation:
Let the volume of paint required to cover whole car be 'x'.
Given:
Volume of paint to cover one-fifth of a car = one-fourth of a gallon.
We use unitary method to determine the volume of paint required.
∵ One-fifth of a car requires paint =
∴ Whole volume of car requires paint =
Therefore, the volume of paint that covers the whole car is gallons or one and a quarter gallons.
