Answer:
D
Step-by-step explanation:
the reason why is because if you put 3 dollars in for the notebooks right you have 3x3=9 and that one pen will be 2 dollars. Now you have 3×2=6 and then the two notebooks will be 6 and you add that and get 12. Hope this helps
Answer:
$23.952, since money is always rounded up $23.96
Step-by-step explanation:
the first step is to get the total value of her purchases, thus we add 16.99 + 12.95 to get 29.94
since she will receive a 20% discount that means that she will be paying 80% of the total value
next we set up the ratio as follows:
portion paid / total = x/29.94 = 80/100
solving the ratio gives you 23.952
By seeing the proportion, we get that approximately, 870 g of rice is required and 130 g of meat is required for the recipe.
We are given that a recipe for two people requires 1kg of rice to 150 g of meat.
That is the proportion of rice to meat is:
1 kg : 150 g
1000 g : 150 g
100 : 15
20 : 3
Now, we are also given that 1 kg that is 1000 g of dish is to be prepared.
Let the portion of rice in it be x.
Portion of meat = 1000 - x
ATQ:
20 : 3 :: x : 1000 - x
20 / 3 = x / (1000 - x)
20,000 - 20 x = 3x
23 x = 20,000
x = 20000 / 23 = 870 ( approx.)
1000 - x = 1000 - 870 = 130.
Therefore, by seeing the proportion, we get that approximately, 870 g of rice is required and 130 g of meat is required for the recipe.
