Question

The clearing house has resistors that sell for $3.50 each and circuit boards that sell for $2.25 each. Write an inequality that represents how many of each type of electronic equipment can be bought with at most $7.​

Answer 1

3.50x + 2.25y smaller than or equal 7

Explanation:

Let x represent the resistor and y represent the circuit board

Resistor: $3.50

Circuit board: $2.25

We know it can be bought at most for $7, so it will be smaller than or equal to $ 7. So, we have equation

3.50x + 2.25y smaller than or equal 7
