Look at this estimate of the cost of a bag of pears that weighs 6.78 pounds.
AleksandrR [38]

Answer                                      

given,                                          

pears that weighs 6.78 pounds.                

statement                                                                  

$1.41 (6.78)  -  $1 * 7 =  $7                

on solving the left hand side of the statement

$1.41 (6.78)  -  $1 * 7 = 9.5598 - 7

     = $ 2.5598                                                          

Left hand side and right hand side is not equal

the estimate is wrong                            

the exact product is equal to $ 2.5598                      

so, we can say that the exact product is less than $7
