QuestionEstimate $391 \times 22$ and explain your method. Also, calculate total costs for items: \$3.47, \$1.99, \$0.25, \$5.

Studdy Solution

STEP 1

Assumptions1. We are estimating the product of391 and22. We are rounding to the nearest ten or hundred for easier multiplication3. We are adding the cost of items purchased at the grocery store

STEP 2

First, let's round391 and22 to the nearest ten. $391 \approx390$ $22 \approx20$

STEP 3

Now, multiply the rounded numbers to estimate the product.
$Estimated\, Product =390 \\times20$

STEP 4

Calculate the estimated product.
$Estimated\, Product =390 \\times20 =7800$

STEP 5

Now, let's move on to the second part of the problem. We need to add the cost of all the items purchased at the grocery store.
$Total\, Cost = \$3.47 + \$1.99 + \$0.25 + \$5$

STEP 6

Calculate the total cost.
$Total\, Cost = \$3.47 + \$1.99 + \$0.25 + \$5 = \$10.71$ So, the estimated product of391 and22 is7800 and the total cost of the items purchased at the grocery store is $10.71.
