Acandle shop sells scented candles for $16 each and unscented candles for $10 each. the shop sells 28 candles today and makes $400.how many scented candles did the shop sell today? how many unscented candles did the shop sell today?

ps: show process!

If x is the number of scented candles and y is the unscented then
16x+10y=400 for cost
x+y=28 for total candles
solve for one and substitute into the other
x+y=28
y=(28-x)
16x+10y=400
16x+10(28-x)=400
16x+280-10x=400
6x=120
x= 20 scented candles

substitute that into one of the original equations to find y
x+y=28
20+y=28
y=8 unscented candles

i believe your answer is b.

good luck!
