Answer:
1 1/2 teaspoon of salt is required
Step-by-step explanation:
The recipe requires 3/4 cup of flour and Nick wants to make the recipe using 1 cup of flour.
The recipe requires 1 1/8 teaspoon of salt and Nick wants to know how much salt he heeds.
Consider short description:
3/4 cup of flour - 1 cup of flour,
1 1/8 teaspoon of salt - x teaspoon of salt.
Mathematically, you can wrte a proportion:
<u>3/4 </u> = 1 / x
<u>1 1/8 </u>
Then
3/4 * x = 1 x 1 1/8,
3x/4 = 9/8,
3x x 8 = 4 x 9,
24x = 36,
x = 36/24 = 3/2 = 1 1/2
Answer:
0.83
Step-by-step explanation:
Answer:
X = (150 - 100) / 5
Step-by-step explanation:
To determine how many DVDs Adam sold in the week, knowing that he charges a fixed amount of $ 100 plus $ 5 for each sale he makes, and in the week he charges a total of $ 150, the following calculation must be made:
X (number of DVDs sold) = (150 (weekly profit) - 100 (fixed amount)) / 5 (value of each DVD)
X = (150 - 100) / 5
X = 50/5
X = 10
So, during the week Adam sold 10 DVDs.
So for the last problem draw out the problem
