The percent of change will be a percentage increase because we go from a smaller number to a larger number. To find a percentage increase, we will use the percentage increase formula:
% increase = final value - original value / original value x 100
Substituting the values in:
% increase = (8,200) - (7,500) / 7,500 x 100, where 8,200 is the new value and 7,500 is the original value.
Simplification after multiplication: 700 / 7,500 x 100
Simplification after division: 0.093 x 100
Simplification after multiplication of 100: 9.333%.
We can round 9.333% down to 9%.
Answer:
15, -7 x=15 y=-7
Step-by-step explanation:
x+y=8, we'll come back to this
x-y=22, move y to the other side, x=y+22
now insert the value of x =(y+22) to the other equation like so, (y+22)+y=8, simplify
2y+22=8 2y=(-14), y=(-7)
Insert the value of y into the first equation again like so, x+(-7)=8, simplify
x=15
15, -7
