20 is how much less than 30? What percent less?
LenKa [72]

Answer:

33.3333% decrease

Step-by-step explanation:

Percent change formula: \frac{(x-y)}{|y|} *100, where x is the new value and y is the starting value.

Plug in values and solve:

\frac{20-30}{30} *100\\\frac{-10}{30} *100\\-0.3333*100\\

-33.3333% change, or a 33.3333% decrease.

Nola purchased 2.5 pounds of cheese for 10. $50 her mother purchased 3 pounds of the same cheese for $12.60 the cost of the chee
Delvig [45]
The answer is 5.2 because if you do 12.60 - 10 it’s 2.6 so you add another 2.6 because it’s 2.6 for a half a pound so if you add the two half of pounds it will add up to one pound so it will be 2.6 + 2.6= 5.2 so basically 5.20$
