Answer:
The answer is B
Step-by-step explanation:
If you look at the graph, you can look at number of tickets and see that to get 10 tickets, you would get charged 80 dollars not 88, so the answer is B
Let
x--------------> ages of Raj
y--------------> age of Zia
we know that
x=y+3-------------> equation 1
x²+y²=369-----------> equation 2
<span>I substitute 1 in 2
</span>
(y+3)²+y²=369----------> y²+6y+9+y²=369---------> 2y²+6y-360=0
2y²+6y-360=0
using a graph tool-----------> to calculate the quadratic equation
see the attached figure
the solution is
y=12
x=y+3--------> x=12+3--------> x=15
the answer is
Raj is 15 years old
Zia is 12 years old
I hope this helps you
