Gina is having a party and wants to spend less that $380. She has already spent $300. The only item left on her list is pizzas, which cost $10 each. How many pizzas, x, can she purchase and stay under her budget? Select the inequality that includes the largest number of pizzas she can purchase and still stay under her budget.

x < 8 (max number of pizzas is 7)

Step-by-step explanation:

set up an inequality where x = number of pizzas

total < 380 (this is given)

total = 300 + 10x (she already spent 300, and each pizza costs 10 each)

300 + 10x < 380

now solve for x

300 + 10x < 380

10x < 80

x < 8

if she wants to spend less than $380, she needs to buy less than 8 pizzas, so she can buy 7 pizzas at most

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

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.
