Can someone please help me with this?

So basically to get the number of photos per page you multiple it by the page # example-5x2=10 5x3=15
To graph it you have to line up the # of pages and the # of photos
Does this help?

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
