I really hope this helps. I’m sure the answer is c:)
Simple, first change the 4.5% into 0.045
Thus,
900=0.045*n
900/0.045=0.045n/0.045
20,000=n
Thus, your answer is 20,000.
Hi
7 = 14.70
15= X
so : X = 15*14.70 /7 = 31.5
15 liters of petrol cost 31.5
x+3<8
8-3 =5
X<5
any number less than 5 will work
8-5=3 is the remaining half
weekly allowance=2(1÷2) where (1÷2) is 3
2×3=6
The weekly allowance should be 6.
