Question

Valentina purchase 200 beads for $48 to make necklaces. If she needs to buy 25 more minutes how much will she pay if she is charge the same rate ?

Answer 1

Valentina has to pay $6 if she'd like another 25 beads.

here's the math:

200b = $48

$1 = (200/48)*b

$1 = (25/6)*b

6*$1 = 6*(25/6)*b

$6 = 25b
