Question

At the farmers market two pounds of peaches cost $4.20.How much will five pounds cost?

Answer 1

$21,00  porque multiplicando $4,20 por 5 da ese resultado

Answer 2

If 2 lbs. is 4.20 we can divide that by 2 to figure out what 1 lbs. costs:
4.20 / 2 = 2.10
Now we know one pound of peaches is $2.10 so you multiply that by 5 to see how much 5 lbs. costs:
2.10 (5) = $10.50
