Savannah washed her neighbor’s cars over the weekend.
She got paid $7.75 for the first car. $8.99 for the second car
and $8.00 for the third car. Savannah was so happy she
shouted, “Wow, I made about $20.00.” Is Savannah’s
statement accurate? Use evidence to support your
thinking.
Yes, her statement is accurate because she added
$7.75 + $8.99 + $8.00 and she got $24.74 and
$24.74 would round down to $20.00.
