Jumbo Market makes $0.10 on a head of lettuce and $0.08 on a bunch of carrots. Last week, a total of 12,900 heads of lettuce and bunches of carrots were sold, with a profit of $1,174. How many heads of lettuce and how many bunches of carrots were sold?
----------
Quantity Equation: L + C = 12,900 items
Value Equation:::10L +8C = 117400 cents
-----
Multiply thru 1st equation by 10:
10L + 10C = 129000
10L + 8C = 117400
---------
Subtract and solve for "C":
2C = 11600
C = 5800 (# of bunches of carrots sold)
---
Solve for "L":
L + C = 12900
L + 5800 = 12900
L = 7100 (# of heads of lettuce sold)
