Adam, Matt, and Clinton sold sandwiches in the ratio of 2:7:3 to raise money their basketball team. Matt sold 91 sandwiches. How many sandwiches did al three boys sell altogether?

156

Step-by-step explanation:

Let,

Sandwiches sold by Adam, Matt and Clinton = 2x, 7x and 3x

Total sandwiches = 2x + 7x + 3x

=> 12x

But its given that Matt sold 91 sandwiches

So,

7x = 91

x = 91/7

x = 13

=> Total sandwiches = 12x = 12(13) = 156

the discriminant is 64 + 4*1*12 = 112

this is prime.
