Question

Brody is purchasing some tools for his workshop. He has a budget of $120 and needs to buy at least 14 tools. Each hammer costs $10, and each wrench costs $6.

Answer 1

He bought 9 hammers and 5 wrenches :). 10(9)+6(5)=120

Answer 2

The graph in the attached figure

Explanation:

Let

x------> the number of hammers

y------> the number of of wrenches

we know that

`10x+6y\leq 120` -----> inequality A

`x+y\geq 14` -----> inequality B

using a graphing tool

The solution of the system of inequalities is the shaded area
