How many loaves of bread did Sam have last Friday? ** If Sam had seventy loaves of bread last Friday, seven times that number is 7*70 = 490 loaves.
How many loaves of bread does the bakery have? ** Since the bakery has 40 less than seven times as many loaves of bread as Sam had last Friday, the bakery has 490-40 = 450 loaves of bread
