A change from 20 to 40 is a 100% increase because the original number was 20. Then, 20 was added to that. So, you are adding the whole number (100%) to itself.

A change from 40 to 20 is a 50% decrease because 40 is being reduced to half of itself (50%).

I hope this helps!

There are 21 jars of peanut butter for sandwiches. Each sandwich uses 1/5 of a peanut butter jar. How many sandwiches can be mad

andrezito [222]

Answer: 105 sandwiches can be made from all the peanut butter.

Step-by-step explanation:

Given: Total jars of peanut butter = 21

Part of peanut butter required for each sandwich = $\dfrac15$

Total number of sandwiches made = ( Total jars of peanut butter ) ÷ (Part of peanut butter required for each sandwich)

$=21\div\dfrac15\\\\=21\times5\\\\=105$

Hence, 105 sandwiches can be made from all the peanut butter.

Umnica [9.8K]

D. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.
