### Problem 22

A survey was given to residents of all 50 states asking
if they had earned a bachelor's degree or higher.
The results from 7 of the states are given in the table
above. The median percent of residents who earned a bachelor's degree or higher for all 50 states was

### Math Test - Calculator - Problem 11

A software company is selling a new game in a
standard edition and a collector's edition. The box
for the standard edition has a volume of 20 cubic
inches, and the box for the collector's edition has a
volume of 30 cubic inches. The company receives an order for 75 copies of the game, and the total volume
of the order to be shipped is $1,870$ cubic inches.
Which of the following systems of equations can be
used to determine the number of standard edition
games, $s,$ and collector's edition games, $c,$ that were
ordered?

\begin{aligned} \text { A) } \quad & 75-s=c \\ 20 s+30 c &=1,870 \\ \text { B) } & 75-s=c \\ & 30 s+20 c=1,870 \end{aligned}

\begin{array}{c}{\text { C) } \quad s-c=75} \\ {25(s+c)=1,870} \\ {\text { D) } \quad s-c=75} \\ {30 s+20 c=1,870}\end{array}
