What is the percent decrease from 60 to 39?

IrinaK [193]

X - the percent decrease

$60-60x=39 \ \ \ |-60 \\
-60x=-21 \ \ \ |\div (-60) \\
x=\frac{-21}{-60} \\ \Downarrow \\ x=\frac{-21}{-60}=\frac{-21 \div (-3)}{-60 \div (-3)}=\frac{7}{20}=\frac{7 \times 5}{20 \times 5}=\frac{35}{100}=35\%$

It's a 35% decrease.

The price of tiling a room varies directly as the size of the room. Sam is laying tile in his kitchen. If the tiling costs $4,22

mixas84 [53]

Answer:

239 ft².

Step-by-step explanation:

Let P represent the price for tiling.

Let S represent the size of the room.

From the question,

Price (P) varies directly as the size (S) i.e

P & S

P = KS

Where K is the constant of proportionality.

Next, we shall determine the value of K as follow

Price (P) = $ 4224

Size (S) = 264 ft²

Constant of proportionality (K) =?

P = KS

4224 = K × 264

Divide both side by 264

K = 4224/264

K = 16

Finally, we shall determine the size of the kitchen that will cost $ 3824 for tiling.

This is illustrated below:

Price (P) = $ 3824

Constant of proportionality (K) = 16

Size (S) =?

P = KS

3824 = 16 × S

Divide both side by 16

S = 3824/16

S = 239 ft²

Therefore, the size of the kitchen is 239 ft².

Andrew [12]

Answer:

$Minimum = \$241786$

Step-by-step explanation:

Given

$Amount = \$228,100$

$Commission = 6\%$

Required

Determine the minimum Katie will list the house

The given minimum is the minimum she can receive for the house after commission

To calculate the listing minimum, we make use of the following:

$Minimum = Amount + Commission * Amount$

$Minimum = \$228,100 + 6\% * \$228,100$

$Minimum = \$228,100 + \$13686$

$Minimum = \$241786$

The minimum She can list the house is $241786
