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 determine 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.

18$-8$book=20pencils that were 10$.

and Brian had 80 cards work: 80÷2= 40+10 new cards=50 cards

for the points! : )

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
