The school that Jeremy goes to is selling tickets to a play. On the first day of ticket sales the school sold 8 senior citizen tickets and 9 child tickets for a total of $188. The school took in $70 on the second day by selling 1 senior citizen ticket and 5 child tickets. What is the price of one senior citizen ticket and one child ticket

x=$10

y=$12

Step-by-step explanation:

Step one:

given

let senior tickets be x

and child be y

8x+9y=1881

also on the second day

x+5y=702

the system of equation is

8x+9y=1881

x+5y=702

x=70-5y, put this in 1

8(70-5y)+9y=188

560-40y+9y=188

-31y=-372

divide by -31

y=-372/-31

y=$12

put y= 12 in x+5y=702

x+5(12)=702

x+60=70

x=$10

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
