Question

66 bats were sold. Some were sold for $42 each the rest were sold for $30 each. The total sales were$2,460. Write and solve a system of equations to find out how many bats were sold for $42 each?

Answer 1

40 bats sold for $42

26 bats sold for $30

Explanation:

x + y = 66

42x + 30y = 2460

solve first equation for y and plug in for y in second equation

42x + 30 (66 - x) = 2460

x = 40

y = 66- 40 = 26
