Question

33 sweatshirts were sold totaling $402.05. White ones sold for $11.95 and yellow for $12.50. How many of each were sold?

Answer 1

a= number of whites,
b= number of yellow,
a+b=33,
a*11.95 +b*12.50= 402.05,
solve for either a or be and plug into the other:

a= 33-b,
(33-b)(11.95)+ b(12.50)= 402.05

plug b into a=33-b once b is known.

Answer 2
