Marci bought 4 yards of ribbon for $6 how much should marci expect to pay for 10 yards of the ribbon?

Vinvika [58]

Ok, let's find how much does 1 yard of ribbon cost. Let's divide!

$6 / 4 = 1.5$

Each yard costs $1.50, so let's multiply that by 10 $1.5 * 10 = 15$

Marci will pay $15 for 10 yards of the ribbon.
