6. The students in Mrs. Bowen'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 a tokens, a bouncy ball
costs b tokens, and a coloring book costs e 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
