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
The amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad is $ 390.24.
Given that:-
Price of the laptop after 1 year = $ 400.
Inflation rate = 2.5 %
We have to find the amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad.
Let the price he had to pay be x.
Hence, we can write,
x + (x*(2.5)*1)/100 = 400
x(1 + 1/40) = 400
x(41/40) = 400
x = 400*40/41 = $ 16000/41 = $ 390.24.
