1. You can call x to the cost of each one of Tanya's items and y to the cost of each one of Tony's items.

2. Based on the information given in the problem and knowing that both paid the same amount of money, you can write the following expression:

5(x-1.25)=4x

3. You must solve for x:

5x-6.25=4x\\ x=6.25

4. The total amount of money that Tanya and Tony paid was:

4x=4(6.25)=25 dollars

5. Therefore, the amount of money that Tony paid for each item was:

y=\frac{25}{5} =5 dollars

The answer is:  The individual cost of each Tanya's items is 6.25 dollars and the individual cost of each Tony's items is 5 dollars.

Please hurry! I'm so confused
Varvara68 [4.7K]

Answer:

Step-by-step explanation:

The general equation is

y = 2.49x + 24.99

The number of cones bought is x

The cake cost is 24.99

The total cost is y

===========

So the meaning of (5,37.44) is that she bought 5 cones and 1 cake. Let's just check that out.

Check

y = 2.49*5 + 24.99

y = 12.45 + 24.99

y = 37.44

So the total cost (y) of 5 cones (2.49 each) and 1 cake ($24.99) is 37.44

A/P = 1 + rt
A/P - 1 = rt

Nataliya [291]

Step-by-step explanation:

The answer is C

We can easily eliminate B and D since Ms. Macdonald isn't starting with 3 rabbits.

We can also eliminate choice A, because 5 to the 3rd power isn't 15.

5 to the 3rd power is 125, therefore the choice is C
