The local hardware store wants to increase their inventory. last year 15 electric screwdrivers cost them $300. at the same cost,

VMariaS [17]

Answer:

Cost of 45 screwdrivers will be = $900

Step-by-step explanation:

Last year 15 electric screwdrivers cost to the local hardware store = $300

So per screwdriver cost = $\frac{\text{Total cost}}{\text{Total number of screw drivers}}$

= $\frac{300}{15}$

= $20

Now we have to calculate the cost of 45 screw drivers.

Since cost of 1 screwdriver = $20

So cost of 45 screwdrivers = 20×45 = $900
