Lizzy: Betty ordered 18 items in an online shop via cash on delivery. She ordered 6 pieces of slippers that cost $2.5 each, 4 pieces of lipstick for $1.25 each, and 8 pieces of hair color for $3 each. How much did Betty pay in total when it was delivered?.
Me: Hmmm, let me think. I think this is the detailed solution:
Betty paid 6 x $2.5 = $15 for the slippers. She paid 4 x $1.25 = $5 for the lipsticks. She paid 8 x $3 = $24 for the hair color. Therefore, Betty paid $15 + $5 + $24 = $44 in total. Final answer: 44.
