Mathematics

Answer:

7/3 is constant of proportionality and, 3/7 of a cup of red paint should be added to 1 cup of white paint.

Step-by-step explanation:

Constant of proportionality is the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.

To make color pink,

for every 3 cups of red , we need 7 cups of white.

Let 'r' be the cups of red required

let 'w' be the cups of white required

so , as per the question

for 3 r we need = 7 w

r = 7/3 w

so, 7/3 is constant of proportionality and, 3/7 of a cup of red paint should be added to 1 cup of white paint.

You already have the answer! ;)

A shirt is originally priced at $24.50. The shirt goes on sale for 30% the original price. How much money, in dollars to the nea
ludmilkaskok [199]

Answer:

The final cost is 1.07($17.15) = $18.35

Step-by-step explanation:

If the discount is 30%, we can find the discounted price by taking 70% of the original price (since 100% - 30% = 70%).  Substitute the equivalent 0.70 to calculate the discount price:  0.70($24.50) = $17.15.  This is the discounted price.

The final cost is $17.15 times 1.07, which includes the discounted price plus the 7% tax.  That final cost is 1.07($17.15) = $18.35.
