The smoke alarms in an office building need new batteries. Larry has 1,311 batteries. Each office in the building needs 6 batteries. How many offices will get new batteries?How many batteries will be left?

218 ; 3

Step-by-step explanation:

Given that:

Total number of batteries Larry has = 1,311

Batteries needed per office = 6

Number of offices that will get new batteries :

Total batteries / batteries needed per office

= 1311 / 6

= 218.5

Take the whole and ignore the decimal :

Hence, 218 offices will get new batteries

Number of batteries that will be left :

Total batteries - (218 * 6)

1311 - 1308 = 3

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
