Jose sells portraits for $300 each. Each portrait costs him $150 in supplies and he spends $2,100 per year on fixed costs. Last year Jose sold 140 portraits. He believes that he made more than $20,000 in profit. Is this true? WILL GIVE BRAINLIEST PLEASE HELP! a) Write an expression to represent José's yearly profit. Use x to represent the number of portraits sold. b) Simplify the expression from Part I. Then, evaluate the expression for the 140 portraits José sold last year to determine if he actually made $20,000 dollars in profit. Write your answer as a complete sentence.

a) y=(300-150)x-2100

b) y=150x-2100

c) y=150(140)-2100

y=18900

Jose was wrong. He did not make 20000 dollars last year.

A: ((300-150) * 140) - 2100

B: 21000-2100= $18,900 profit.

Jose made 18,900 dollars worth of profit. He did not make $20,000 worth of profit.

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
