Acafeteria worker is wondering how student lunch prices at a high school have changed over time. she researches lunch prices for the years 2000-
through 2015 and plots the data in a scatter plot. the best-fit line for the data has the equation y = 0.057 x + 1.150, where x is the number of years
since 2000 and y is the student lunch price, in dollars.
determine whether each statement below is true or false based on the equation of the line of best fit. select true or false for each statement

true false
the student lunch price was generally increasing between 2000 and 2015.

the student lunch price changed by approximately 5.7 cents per year.

the student lunch price in 2015 was approximately $1.15.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

step-by-step explanation:

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
