Question

sam spent $54.60 on games for her little brother. she spend 25% more on games for herself. what was the total cost brought for herself and her little brother?

Answer 1

Ok so first you have to find what 25% of 54.60 is:
we will make that stand for x
x/54.60=25/100
cross multiply
54.60(25)=1365
100(x)=100x
1365=100x
divide both sides by x
x=13.65
so you know that 25% of 54.60 is $13.65
Because she is spending more you add this to the 54.60
54.60+13.65=$68.25
