If dave had 5 apples, sandie has twice the amount dave has.

how many apples does sandie have?

10

Step-by-step explanation:

If Dave has 5 apples and Sandie has double the amount then you need to multiply 5 and 2.

5×2=10.

First it’s twice 5 so basically you multiply( 5•2)=10 or add (5+5)=10 so if Dave has 5 apples sandie has 10 apples

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
