Answer:
The sold 354.5 hamburgers and 300.5 cheeseburgers.
Step-by-step explanation:
Let number of hamburgers=h
Let number of cheeseburgers=c
On Sunday, the shop sold a combined total of 659 hamburgers and cheeseburgers. Therefore:
h+c=659....(I)
There were 50 fewer cheeseburgers sold than hamburgers .
c=h-50.....(ii)
Substitution of equation (ii) into (I)
h+(h-50)=659
2h=659+50
2h=709
h=709/2=354.5
From (ii)
c=h-50
=354.5-50=300.5
The sold 354.5 hamburgers and 300.5 cheeseburgers.
NOTE: These result are from the given data. However, we were not informed if the shop sells half burgers or not
Kyle purchased a 20 lb. pumpkin for $5.95.
Cost per lb of pumpkin for Kyle = 5.95/ 12 = $0.496.
Elizabeth purchased a 15 lb. pumpkin for $5.00.
Cost per lb of pumpkin for Elizabeth = 5.00/15 = $0.333.
Elijah purchased an 8 oz. pumpkin for $ 0.16.
16 oz = 1 lb
8 oz = 0.5 lb.
Cost per lb of pumpkin for Elijah = 0.16/ 0.5 = $ 0.32.
<h3>Cost per lb of pumpkin for Elijah is $ 0.32 is the lowest price per lb of pumpkin .</h3><h3>Cost per lb of pumpkin for Kyle is $ $0.496 is the highest price per lb of pumpkin .</h3><h3>Therefore, Elijah got the best deal and Kyle got the worst deal.</h3>
