Answer:
Demetrius took 61.5 ≈ 62 photos
Explanation:
total photos taken = 115
if both took an equal number of photos
then Brooklyn = 50% of 115
Demetrius = 50% of 115
4 photos out of 115 will be = 4/115 * 100% = 0.0347 * 100 = 3.48 %
If Demetrius took 4 more photos then Demetrius will be taking = 50% + 3.48%
= 53.48%
If Brooklyn took 4 less photos then Brooklyn will be taking = 50% - 3.48%
= 46.52%
therefore Demetrius took = 53.48 % of 115
= 61.5 ≈ 62
