Ruth bought cutter s and screwdrivers to upgrade the computers in her company. a cutter costs 15.2$ and a screw driver costs $2. she bought a total of 29 tools and spent 150.40$. how many of each tool did ruth buy?

The number of cutters is 7

The number of screw drivers is 22

Step-by-step explanation:

Let

x-----> the number of cutters

y----> the number of screw drivers

we know that

x+y=29 ----> equation A

15.2x+2y=150.40 ----> equation B

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution is the point (7,22)

see the attached figure

therefore

The number of cutters is 7

The number of screw drivers is 22
