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

30% of 30
Well, when doing a percentage you first turn the percentage into a decimal (move the % two units to the left). So 30% = 0.3
In math, the word of means multiplication, so: 0.3 x 30
Which equal 9.
You can also turn the percentage into a fraction, it's really up to preference.
30/100 of 30 = 3/10 of 30 = 3/10 x 30 = 3/10 x 30/1 = 9/1 or 9
-4 1/8 as decimal.
The decimal is -3.875.
