Question

A set of 6 pens cost $2.34. A set of 20 pens is sold at the same unit price what is the cost for 20 pens

Answer 1

$10.80 I think is the answer

Answer 2

I hope I'm not to late. Since 6 pens cost 2.34, you need to divide 6 into 2.34 which is 0.39. 0.39 x 20 is 7.8, so the answer is $7.80
