20. Mackenzie has made 21 of her last 30 free throws which is an average of 70%. A. Write a function to model Mackenzie's rate of success if she makes x more
consecutive free throws.

 Either 70% or S=0.7x

Step-by-step explanation:

I'm unclear as to what the question really wants.  A "rate of success" is simply an expected percentage of future shots that will score on a free throw.  Since the only statistic we are given is the 70%, it would seem that would also be the rate of success for future shots.

If the question is seeking the actual number of successful free throws, S, in the next x shots, the expression would be:

S = 0.70x

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
