Answer:

Step-by-step explanation:

To perform this multiplication I would rewrite the expression as

81*4*100. This is easier to do mentally: 4 times 81 is 324, and then 324 times 100 is 32,400. There are of course other approaches involving factoring the original expression and performing multiplication.

Wanda wants to buy 4.35 pounds of chicken salad. The grocery store sells chicken salad for $2.29 a pound. How much does the chic

LenKa [72]

This is very simple.

If you want 4.35 pounds, and it's 2.29 a pound, you simply multiply 4.35 by 2.29.

4.35 * 2.29 = 9.9615 or 10

The chicken salad costs $9.9615 or $10, whichever you need.
