Question

To support a local charity, a community center hosted a bake sale. Cookies were sold for $2 each, and cakes were sold for $10 each. A total of $800 was raised from the bake sale.

a) Which equation can be used to represent how many cookies ( c
) and cakes ( k
) were sold?

b) If the community center sold a total of 36 cakes, how many cookies did they sell? cookies were sold.

Answer 1

a) 2c + 10k = 800 (or simplified: c + 5k = 400)

b) If k = 36: c + 5(36) = 400 → c + 180 = 400 → c = 220.

So 220 cookies were sold.
