Drag each scenario to show whether the final result will be greater than original value less than the original value was the same as original value

answer: whenever you have an increase, you multiply by (100% + increase%) and whenever you have a decrease you multiply by (100% - decrease%). so for each pair, let's do that. a 30% increase followed by a 15% decrease. = ? (1 + 0.3)*(1 - 0.15) = 1.3*0.85 = 1.105. result is greater than original. a 70% increase followed by a 50% decrease. = ? (1 + 0.7)*(1 - 0.5) = 1.7 * 0.5 = 0.85. result is less than original. a $35 decrease followed by a $25 increase = ? tricky. no percentages. so -35 + 25 = -10. so value is less than original. a 50% increase followed by a 33/1/3% decrease. = ? (1 + 0.5)*(1 - 0.) = 1.5 * 0.7 = 1. result is same as original. a 50% decrease followed by a 100% increase. = ? (1 - 0.5)*(1 + 1) = 0.5 * 2 = 1. result is same as original.

(c, 0) i might be wrong so don't put full faith on my answer

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
