Hugh has to earn at least $400 to meet his fundraising goal. He has only 100 books that he plans to sell at $8 each. Which inequality shows the number of books, x, Hugh can sell to meet his goal?

#8x\ge400#

Hugh needs to earn (#y#) at least 400 dollars. #y\ge400# Given #x# books sold at 8 dollars each, #8x#
Hugh's earnings #y#... #8x=y\ge400# #8x\ge400#

# x >= 50#

Total funds: #T=x*8#

to meet his goal:

#T>= 400#
so # x*8 >= 400#

multiply both sides by 8

# x >= 400/8#

simplify the fraction

# x >= 50#
