Lisa and Daisy work at a hair salon. The salon charges $21 for a hair styling session with Lisa and $17 for a session with Daisy

.
Their income on a certain day is projected to be $357. This situation can be represented by the equation 21x + 17y = 357, where x is the number of Lisa's customers and y is the number of Daisy's customers.

(Technical details: x ≥ 0, y ≥ 0, and x and y take only integer values.)

How many customers would Lisa need to serve to attain the projected income if Daisy calls in sick that day?

Given:

The table of values.

To find:

The function for the given table.

Solution:

From the given table it is clear that the y-values are same as the corresponding x-values. It means y is directly proportional to x with 1 as a constant of proportionality.

Mathematically, it can be defined as:

y=1\times x

y=x

Substitute y=f(x) in the above equation to find the required function.

f(x)=x

Therefore, the correct option is A.

If a car factory checks 320 cars and 12 of them have defects, how many out of 560 will have defects? Use proportions
Viefleur [7K]

Answer:

Total number number of cars which do not have defects = 539

and 21 are defected out of 560 i.e. 560 - 539 = 21

Step-by-step explanation:

Total cars checked by Car factory = 320

Number of defected cars = 12

The number of cars which do not have defects = 320 - 12 = 308

Total Number of cars = 560

So the equation becomes

\left[560\:\times \:308\right]\:\div \:320

⇒  \frac{560\times \:308}{320}

\mathrm{Multiply\:the\:numbers:}\:560\times \:308=172480

⇒  \frac{172480}{320}

\mathrm{Divide\:the\:numbers:}\:\frac{172480}{320}=539

⇒  539

Therefore, total number number of cars which do not have defects = 539

and 21 are defected out of 560 i.e. 560 - 539 = 21
