Grace bought a book for $8 and some pencils that cost $.50 each. She spent a total of $18. Write and solve an equation to determ
ine how many pencils she bought. Let p represent the number of pencils she bought. Brian sold half of his baseball cards. The next day, he bought 10 more. Now he has a total of 50 cards. Write and solve an equation to determine how many baseball cards he had before he sold any. Let b represent the number of baseball cards he had.
If the notebook is $8 and you spend $18 that means you brought 10 worth of pencils.
50c - 1pencil $1 - 2 pencils $1.50 is 3 $2 is 4 $2.50 is 5 $3.00 is 6 $3.50 is 7 $4.00 is 8 $4.50 is 9 $5.00 is 10
Then you have spent $5 on pencils in that and then you double it so you then have 20p for $10 :)) then $10 + 8 is $18 and in the problem you spent $18 x
