Jo thinks she must have sold more than 200 cups of coffee. Is jo correct?

Respuesta :

Answer:

No, the thought is wrong

Step-by-step explanation:

Here, we want to check if Jo is correct

The ratio we have is tea cups to coffee cups of ratio 1:3

Now, there are 244 cups of coffee

Now let’s say the total number of cups is x

For the ratio to be correct

Then;

3/4 * x = 244

x = (244*4)/3

x = 325

Now let’s subtract the number of cups

That will be;

325 - 244 = 81

This means the number of cups she thought was incorrect
