The volume of dry goods, like apples or peaches, can be measured using bushels, pecks, and quarts. A bushel contains 4 pecks, and a peck contains 8 quarts.
What is the relationship between number of bushels, b, and the number of quarts, q?
32q = b
The knitting club sold 40 scarves and hats at a winter festival and made $700 from the sales. They charged $18 for each scarf and $14 for each hat.
If s represents the number of scarves sold and h represents the number of hats sold, what system of equations represents the constraints in this situation?
s + h = 40
18s + 14h = 700
The soccer team is selling bags of popcorn for $3 each and cups of lemonade for $2 each. To make a profit, they must collect a total of more than $120. Write an inequality to represent the number of bags of popcorn sold, p, and the number of cups of lemonade sold, l, in order to make a profit.
3p + 2c > 120

This year, students in the 9th grade are collecting dimes and quarters for a school fundraiser. They are trying to collect more money than the students who were in the 9th grade last year. The students in 9th grade last year collected $143.88.
Using d to represent the number of dimes collected and q to represent the number of quarters, write an inequality for this problem.
0.25q + 0.1d > 143.88

Elena is considering buying bracelets and necklaces as gifts for her friends. Bracelets cost $3, and necklaces cost $5. She can spend no more than $30 on the gifts. Elena needs at least 7 gift items. Write a system of inequalities that represents the number of gift items that Elena needs.
3b+5n <= 30
b + n >= 7
Function f is defined by f(x) = x2
Explain why f(2) + f(3) is not equal to f(5).
f(2) = 4 f(3) = 9 f(5) = 25
4 + 9 != 25
