12345 [234]

Answer:

1 1/8 cup of brown sugar.

Step-by-step explanation:

Here is the correct question: A recipe calls for 3/4 cup brown sugar for  each 2/3 cup white sugar. How many cups of  brown sugar per cup of white sugar is this?    

Given: 3/4 cup of brown sugar for each 2/3 cup of white sugar.

Finding requirement of brown sugar for 1 cup of white sugar.

∴ Each 2/3 cup of white sugar require 3/4 cup of brown sugar.    

Now, 1 cup of white sugar require brown sugar = \frac{\frac{3}{4} }{\frac{2}{3} } cups

 = \frac{3}{4} \times \frac{3}{2} = \frac{9}{8} \ cup

Thus, we can say \frac{9}{8} = 1 1/8 cup of brown sugar is required per cup of white sugar.

Item 1: sleeved dress $17.99
Oksana_A [137]

Answer:

<em>The final price including tax is $41.89</em>

Step-by-step explanation:

The following items are on sale:

Sleeved dress $17.99

Skirt $16.19

T-shirt $8.99

Subtotal $43.17

The cheapest item is the T-shirt for $8.99 and it will be discounted by 30%:

$8.99 - 30/100 * $8.99 = $8.99 - $2.70 = $6.29

The total sale price is now: $43.17-$2.70=$40.47

Now we add the 3.5% tax:

$40.47 + 3.5/100 * $40.47 = $40.47 + $1.42 = $41.89

The final price including tax is $41.89
