Step-by-step explanation: ummnmm i think 18
you would use 1.5 packets, but that requires 2 packets.
1 packet in total would feed 8 people, and half of another would feed an extra 4. 4+8 = 12.
30% of the 30 marbles is nine and 9-30 = 21 so your answer is 21
The total price before tax is $(38.75 +41.10) =79.85 and after tax the purchase price is 79.85 x 9.5% = $7.59 + $79.85= $87.44
