Answer:
All of the above
Step-by-step explanation:
Making a good purchasing decision requires comparing the prices of similar items,
reading reviews of the product and waiting until the product is on sale, if possible.
For a consumer to make the best purchasing decision, he needs to compare the prices of similar product or substitute so as to maximize utility. The aim to buy a good quality product at less price.
The Consumer also needs to read the review of the product made by previous users of the product. This is to ensure that he makes he doesn't make the mistake of purchasing low quality product.
He also needs to wait until the product is on sale before deciding on purchasing it. This is to there is no regret of purchasing a product that is of low quality later in the future.
There is an error in the equation provided. Looking at other similar question such as this, I think the equation related to x and y should be 90x + 1600 = y
Answer:
a) 90
b) 1600
Step-by-step explanation:
The equation 90x + 1600 = y is an equation of a straight line in the form y = mc + c
Adjusting the equation to the general form we get
y = 90x + 1600
m = 90
c = 1600
a) the change in Mary's total pay for each copy she sells in this case is referring to the change of y to the change of x.
In other word, it is the slope of the function.
m = 90
b) if Mary didn't sell any copies, the value of x will be 0.
In graph of a straight line, the value when x= 0 is at the value of y-intercept,
c = 1600
