First, we are told that Noah bought 4 tacos and paid $6.
Therefore:
Cost of One taco
[tex]\begin{gathered} =\frac{6}{4} \\ =\$1.5\text{ per taco} \end{gathered}[/tex]Therefore, at this rate:
[tex]\begin{gathered} 1.5=\frac{15}{n} \\ 1.5n=15 \\ n=\frac{15}{1.5} \\ n=10 \end{gathered}[/tex]Noah can buy 10 tacos for $15.
On the other hand, Jada's family bought 50 tacos for a party and paid $72.
[tex]\begin{gathered} \text{Jada's family rate}=\frac{72}{50} \\ =\$1.44\text{ per taco} \end{gathered}[/tex]We conclude that Jada's tacos were not the same price as Noah's tacos.
