Step-by-step explanation:
I think it’s $1.35 sorry if I’m not correct
In order to use the elimination method<span>, you have to create variables that have the same coefficient—then you </span>can eliminate<span> them. Multiply the top </span>equation<span> by 5. Next add the </span>equations<span>, and </span>solve<span> for y. Substitute y = 10 into one of the original </span>equations<span> to find x.</span>
A*5+b*2=145
a +b =50 | * -2
5a +2b=145
-2a -2b = -100
----------------------
5a-2a = 145-100
3a= 45
a=45:3
a=15 questions are worth 5 p
b=50-15=35 questions worth 2 p
