Answer :
A.
If we represent the number of candles by y, since each box can fit 15 candles, the function that represents the number of candles and the number of boxes is:
[tex]y=15x[/tex]B.
If we have 75 candles, let's use y = 75, then we can find the number of boxes x:
[tex]\begin{gathered} 75=15x \\ x=\frac{75}{15} \\ x=5 \end{gathered}[/tex]So we need 5 boxes to pack 75 candles.
