Producing 240 units costs a factory $1,680 in materials. If material costs stay proportional, what would 325 units cost in materials?

Correct answer to question 193 (Arithmetic Reasoning): $2,275

Method

First find the cost per unit: 1,680 divided by 240 is $7.00 per unit. At that rate, 325 units would cost 325 x 7, which is $2,275.
