Answer: 925 pages
Step-by-step explanation:
From the question, we are told that with a full ink cartridge, a printer can print 2,500 pages but that the printer cartridge is now 37% full.
The best estimate of the number of pages the printer can still print will be calculated as:
= 37% × 2500
= 0.37 × 2500
= 925 pages
225, the square root of 225 is 15
