Answer:
Use this pencentage change formula:
New - Old
---------------- x 100
Old
Step-by-step explanation:
390 + 35.10 = 425.1 (New value)
So apply this to the formula:
425.1 - 390
--------------- x 100
390
<em>Which is = 9%</em>
<em>Hope</em><em> </em><em>it</em><em> </em><em>helps</em><em>.</em><em> </em><em>Cheers</em><em>!</em><em> </em><em>:</em><em>)</em>
4*25= 100 (total points)
x + y = 24 4x-2y = 66
since he only answered 24 questions
therefore max he can get is 96
x + y = 24
4x-2y = 66 from first equation,
y = 24-x plug that in second equation :
4x - 2(24-x) = 66
4x - 48 + 2x = 66
6x = 114
x = 19
