At Dunkin Donuts store, the ratio of donuts topped with vanilla frosting to donuts topped with glaze was 4:7 on Sunday. The store made a total of 132 donuts that day. How many donuts were topped with glaze?

Respuesta :

Let the donuts topped with vanilla frostings be 4x and donuts topped with glaze be 7x.

The total number of donuts is 132. So equation for x is,

[tex]\begin{gathered} 4x+7x=132 \\ 11x=132 \\ x=\frac{132}{11} \\ =12 \end{gathered}[/tex]

Determine the number of donuts topped with glaze.

[tex]\begin{gathered} 7x=7\cdot12 \\ =84 \end{gathered}[/tex]

So answer is 84.
