Katie is getting her laundry done it cost $2.25 per square foot of flowers added to the yard if she wants 12.4 ft.² of flowers h
7nadin3 [17]

Answer:

Katie needs to pay $27.9.

Step-by-step explanation:

Given;

Cost of per foot = $2.25

Number of  flowers in her yard = 12.4 square foot

We need to find how much she needs to pay.

Solution:

Now we know that;

1\ ft^2 = \$2.25

So for 12.4 ft^2 = Cost for 12.4 ft^2 .

By using Unitary method we get;

Cost for 12.4 ft^2 = 2.25\times12.4= \$27.9

Hence Katie needs to pay $27.9.

Pls help me
Mashutka [201]

Answer:

A is the answer because...

Step-by-step explanation:

Let's narrow it down, so it is not D because 8/2=4 but 64/4=16, so already they don't share a slope. It is not B because the numbers don't work together like they should, since we are trying to prove proportionality. It is not C because we are not trying to square the numbers but find a similarity between the numbers, the same slope I mean. So that leaves A which has  the slope of 2, test it out now. 0 and 0 are the same, 4/2=2, 8/4=2, 12/6=2. So now you know that A is the correct answer.

Hope you understand! :)
