Renata and her family go through an average of more than 15 cans of sparkling water each day. They buy cases of 24 cans at $3.50 a case. Write an inequality for the number of cases they go through in 30 days.

Step-by-step explanation:

We are given the following in the question:

Let x be the total number of sparkling cans of water used in a day.

The family uses more than 15 cans each day so inequality becomes,

Number of cans in 30 days

The family buys case of water with 24 cans in each case.

Number of cans used in a day is more than 15, so approx number of cans used in 30 days will be =

Thus, the family buys around 19 cases or more of sparkling water in 30 days.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
