Mato is making a leather belt inlaid with beads. On the first day there were b beads on the belt. On the fourth
day, there were b3 beads on the same belt. There
were 216 beads on the belt on the fourth day.

It’s either a or c as the answer.

Okay so n is going to represent our first number. since the second number of five times greater than n, the second number will be represented as 5n. for us to figure out the two  numbers we need to have  the value of n first. this is going to be done by adding the two numbers together, n and 5n. it can be simplified as 6n, which the problem states is equal to 72. divide 72 by 6n and you can solve for n.  n+5n=726n=72n=(72/6)n=12  now that we know the value of n, we have to multiply 5 times 12 which equals 60. so our two numbers/integers are 12 and 60
