Spencer is making 25 sundaes with mint, chocolate, and vanilla ice cream. 1 5 of the sundaes are mint ice cream and 1 2 of the remaining sundaes are chocolate. The rest will be vanilla. How many sundaes will be vanilla?

v = 20 Sundaes

Step-by-step explanation:

Total number of sundaes = 25

Let the number of mint = m = 1/5 of total

= 1/5 of 25 = 1/5 × 25 = 5

∴ m = 5

Remainder = 25 - 5 = 20 Sundaes

let the number of chocolate = c = 1/2 of the remainder

1/2 of remainder = 1/2 of 20 = 20 ÷ 2 = 10 sundaes

∴ c = 10

let the number of vanilla = v

Therefore, finding v

25 = m + c + v

25 = 5 + 10 + v

25 = 15 + v

25 - 15 = v

v = 20 Sundaes
