Answer:
14
Step-by-step explanation:
perimeter = sum of all sides
so 75- (15+10+27+9)
= 75- 61
= 14
If the rate is $3.50 for a five-pound bag, then the unit rate is $0.70 per a pound bag.
So first we need to find the total number of boxes that the cookies could fit in:
Now we know that 47 boxes were made from this amount of cookies.
If Mr. Riley sells each box for 8, then we need to multiply the number of boxes by 8:
So Mr. Riley will collect a total of 376 from selling all of his cookies.
