3.) john spends $81 on food during his vacation.
that is 45% of the money he brought with him.
how much money does john have left to
spend?

John has 99 dollars after spending on food

Step-by-step explanation:

The total amount John brought with him during his vacation can be expressed as;

Total amount John has=Amount he spends on food+amount he has left after spending on food

where;

Total amount John has=x

Amount he spends on food=45% of x=(45/100)×x=0.45 x

Amount he has left after spending on food=(Total amount he has-amount he spends on food)

Amount he has left after spending on food=(x-0.45 x)=0.55 x

Equating the amount he spends on food to 0.45 x;

0.45 x=81

x=81/0.45

x=180

Amount he has left after spending on food=(x-0.45 x)=0.55 x

Replacing the value of x;

Amount he has left after spending on food=(0.55×180)=99

John has 99 dollars after spending on food

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
