The sunshine tool company charges $25 for hammers and $14 for screwdrivers. the company ships a total of 55 tools along with the bill of $968.How many of each tool was shipped?

Answer 1

X = The # of hammers.
Y = The # of screw drivers.

Eq1: X + Y = 55,
Eq2: 25X + 14Y = 968
Multiply both sides of Eq1 by -14:
-14X + -14Y = -770,
25X + 14Y = 968,
Sum: 11X = 198,

X = 18 Hammers.
Y = 55 - 18 = 37 Srewdrivers.
