Question

jos donut express earned $4,378 at a festival by selling chocolate or vanilla donuts for $2 each. if they sold 978 chocolate donuts, how many vanilla donuts did they sell?

Explanation:

Step1: Calculate total donuts sold

Let total donuts sold be \( T \). Each donut is $2, total earnings $4378. So \( T=\frac{4378}{2} \)
\( T = 2189 \)

Step2: Find vanilla donuts sold

Let vanilla donuts be \( V \), chocolate donuts \( C = 978 \). \( T = V + C \), so \( V = T - C \)
\( V = 2189 - 978 \)
\( V = 1211 \)

Answer:

1211
