Find the number of Calories in a grapefruit and an orange.

(1) An orange has 15 more Calories than a grapefruit.
(2) Twenty oranges and ten grapefruit have 1800 Calories.

Well, it seems like we have a fruity calorie mystery on our hands! Let's get to the bottom of it with some clownish deduction.

From statement (1), we know that an orange has 15 more calories than a grapefruit. But since we don't know the exact number of calories in either fruit, we can't determine their individual calorie counts.

Now, let's move on to statement (2), which tells us that 20 oranges and 10 grapefruits together have 1800 calories. Unfortunately, this still doesn't help us find the individual calorie counts for each fruit because we don't know the ratio of oranges to grapefruits.

So, it looks like we've reached a fruity dead-end. We can't determine the specific calorie counts for a grapefruit and an orange based on these statements alone. Guess we'll have to enjoy them and their juiciness without worrying about the calories!

Let's assign some variables for easier referencing. Let's say the number of calories in a grapefruit is 'G' and the number of calories in an orange is 'O'.

From statement (1), we know that "An orange has 15 more Calories than a grapefruit." This can be expressed as:
O = G + 15 ---(Equation 1)

From statement (2), we know that "Twenty oranges and ten grapefruit have 1800 Calories." This can be expressed as:
20O + 10G = 1800 ---(Equation 2)

We can now solve the two equations simultaneously to find the values of 'G' and 'O'.

Let's substitute the value of (O) from Equation 1 into Equation 2 to eliminate (O):
20(G + 15) + 10G = 1800
20G + 300 + 10G = 1800
30G + 300 = 1800
30G = 1500
G = 1500/30
G = 50

Now, substitute the value of (G) back into Equation 1 to find (O):
O = 50 + 15
O = 65

Therefore, the number of calories in a grapefruit is 50, and the number of calories in an orange is 65.

To find the number of Calories in a grapefruit and an orange, we can use the information given in the two statements and solve the problem step-by-step.

Let's assume the number of Calories in a grapefruit is "G" and the number of Calories in an orange is "O".

Statement (1) tells us that an orange has 15 more Calories than a grapefruit. Mathematically, we can write this as:
O = G + 15.

Statement (2) states that twenty oranges and ten grapefruit have 1800 Calories. Mathematically, we can write this as:
20O + 10G = 1800.

Now, we can set up a system of equations using the information from both statements:

Equation 1: O = G + 15 (from statement 1)
Equation 2: 20O + 10G = 1800 (from statement 2)

We can now solve this system of equations to find the values of G and O.

Rearranging Equation 1, we get:
G = O - 15.

Substituting this value of G into Equation 2, we have:
20O + 10(O - 15) = 1800.

Expanding and simplifying this equation:
20O + 10O - 150 = 1800,
30O = 1950,
O = 65.

Now, substitute this value of O back into Equation 1 to find the value of G:
G = O - 15,
G = 65 - 15,
G = 50.

Therefore, the number of Calories in a grapefruit is 50, and the number of Calories in an orange is 65.

G = Grapefriut calories, R = oRange Calories

G = R - 15

20R + 10G = 1800

Substitute R - 15 for G and solve for R in second equation. Put that value in the first equation to find G. Check by putting both values in the second equation.
