The students in Mrs. Wolford's kindergarten earn tokens that they can use in the class store to get prizes.
There are three different prizes available: stickers, bouncy balls, and coloring books. The number of tokens
needed for each prize varies. A sticker costs s tokens, a bouncy ball costs b tokens, and a coloring book
costs c tokens. The system of equations shown gives the total number of tokens spent by three different
students. How many tokens are needed to get a coloring book?
s+b+2c= 26
4s = 8
3b+c=22
