The two-way table shows the number of houses on the market in the Castillos’ price range. A 6-column table has 4 rows. The first column has entries 1 bathroom, 2 bathrooms, 3 bathrooms, total. The second column is labeled 1 bedroom with entries 67, 0, 0, 67. The third column is labeled 2 bedrooms with entries 21, 6, 18, 45. The fourth column is labeled 3 bedrooms with entries 0, 24, 16, 40. The fifth column is labeled 4 bedrooms with entries 0, 0, 56, 56. The sixth column is labeled Total with entries 88, 30, 90, 208.

What is the probability that a randomly selected house with 2 bathrooms has 3 bedrooms?

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
