19a) Write a subtraction sentence to complete the fact family for: -6 + n = 25
19b) Find the value of n from the problem above.
Malory wants to take four of her friends to a movie. She knows it costs $4.75 for a ticket and
$4.25 for popcorn.
20a) How much will it cost if she pays for the movie and popcorn for all five people?
20b) Write a number sentence to show how you found the total cost.
21) Write a new number sentence that shows a different way to find the total cost. Explain.
22) Find the values of x that satisfy the inequality 𝑥 + 6 < 10. Then graph the solutions for x
on the number line, and write the answer as an inequality sentence.
The table below gives monthly average low temperatures (in degrees Fahrenheit) from
November through March for International Falls, Minnesota.

19a) Write a subtraction sentence to complete the fact family for: -6 + n = 25
25 – (-6) = n
19b) Find the value of n from the problem above.
N = 31
Malory wants to take four of her friends to a movie. She knows it costs $4.75 for a ticket and
$4.25 for popcorn.
20a) How much will it cost if she pays for the movie and popcorn for all five people?
$45
work: 4.75 * 5 = 23.75 and 4.25 * 5 = 21.25, then add the answers
20b) Write a number sentence to show how you found the total cost.
(4.75 + 4.25) * 5
OR
(4.75 * 5) + (4.25 * 5)
21) Write a new number sentence that shows a different way to find the total cost. Explain.
See above, whatever sentence is not used, put the other here. Use the distributive property to
expand or to factor.
22) Find the values of x that satisfy the inequality 𝑥 + 6 < 10. Then graph the solutions for x
on the number line, and write the answer as an inequality sentence.
x < 4 Remember to first solve, then put a circle at 4 on the number line. It is open, since 4 is
not part of the answer. Think: shade all numbers less than 4
The table below gives monthly average low temperatures (in degrees Fahrenheit) from
November through March for International Falls, Minnesota.

23) What is the mean of the monthly low temperatures? Show your work.
Remember the mean is the average of all the numbers (add all the numbers, then divide by
number of months.)
The mean (average) is – 0.6 work: (15+-9+-13+4) then divide by 5
24) What is the difference of the highest and lowest temperatures?
28 degrees or 28 spaces (this is the range)
