A print shop uses 150 millilitres of ink for 6 posters of the same design and size. How many millilitres are needed for 14 posters? Enter the number of millilitres.
Richtige Antwort
350
Erklärung
The shop uses 25 millilitres per poster because 150 divided by 6 is 25, and 14 times 25 is 350. Adding only the eight extra posters to 150 would produce 158, confusing a change in item count with a change in ink volume.
