156 divided by 8 is 19.5 i think the answer is 19
she needs to get at least how much she needs
how much she gets=number of candles per pack times number of packs
how much she gets=8*n

how much she needs =156

156≤8n
divide both sides by 8
19.5≤n
yo can't buy 19.5 packs, so round up
20 packs should be purchased
