Question

That is buying paper cups and plates cups come in packages of 10 and please come in packages of 15 she wants to buy the same number of cups and plates plans to buy the least number of packages passports how much should not expect to pay each package of cups for six dollars and each package of places eat dollars show your work

Answer 1

10 = 5*2

15=5*3

the least common multiple for 10 and 15 is 5*3*2 or 30

so she needs 3 packages of 10 cups and 2 packages of 15 plates

If cups cost 6 dollars 6*3 = 18

if plates cost 8 dollars(?) 2*8 =16

18+16 = 34 dollars
