When the price is $ 40 per radio, a producer will supply 90 radios each month for sale. for each $4 increase in price the producer will supply an additional 8 radios. how many radios are supplied if their per unit price is $76

Price for a radio = $ 40 for supply 90 radios in a month.

Ratio of increase in price to the number of radios supplies in a month 4:8 that is 1:2.

New unit price given  = $76.

Difference in unit price given in starting and New unit price = 76-40=$36

So, increase in unit price = $36.

Let us assume number of supplied increased  = x radios for increase in unit price $36.

So, we can setup a perportion as,

1/2 = 36/x.

On cross multiplication, we get

1*x = 2*36

x= 72.

So, 72 is the increased number of radios in 90 radios.

That is 72+90 = 162 radios each month.

Therefore, 162 radios are supplied if their per unit price is $76.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

246
