Answer:the selling price if payment is made in cash is $395
Step-by-step explanation:
The list price of the computer software program is $500
A dealer offers the computer software program at a 19% discount.
She will give an extra 3% discount if paid in cash. This means that the total discount in percentage if a customer paid in cash would be
19 + 3 = 21%
The value of the discount would be
21/100 × 500 = 0.21 × 500 = $105
Therefore, the selling price if payment is made in cash would be
500 - 105 = $395
Answer:
the second one
Step-by-step explanation:
To solve this problem we can set up a proportion, letting x represent the unknown amount of cooking oil.
30 milliliters water/20 milliliters cooking oil = x milliliters water/ 50 milliliters cooking oil
30/20 = x/50
To solve this proportion, we can use cross products, also called the means extremes products theorem. This takes the products of the numerator and denominator from the separate fractions and sets them equal to one another. In this circumstance, it results in the equation:
(30)(50) = (x)(20)
When we multiply we get:
1500 = 20x
Finally, we have to divide both sides of the equation by 20 to get our variable x alone on the right side of the equation.
x = 75 milliliters
Therefore, the proportion is completed, as 30/20 = 75/50.
Answer: You need 75 milliliters of water.
