A company wants to spend equal amounts of money for the purchase of two types of computer printers costing \$600 and \$375 per unit, respectively. What is the fewest number of computer printers that the company can purchase?

a. 13
b. 12
c. 10
d. 8
e. 5

I wasn't too sure how to set-up the equation for this one. What i can extract from the q stem is 600x = 375y. But then what? Is this a case of backsolving?

I think the Ans is A... but may b wrong as I have tried to solve this in a hurry.

We know that...
600x = 375y

x/y = 5/8

Now try dividing the numbers given in this ratio....The only possible choice is A

I got A as well,

using LCM formula

LCM for 600 and 375=3000, therefore 5 + 8=13 computers

600/375 = 8/5

That means 5 times 600 and 8 times 375 yield the same result = 3000. Therefore the company can spend equal amounts on both printers by buying 5 of the 600 variety and 8 of the 375. Thus total becomes 13
