Hello I'm like kind of 'stumped' with this question can you fellow people help me out there??



The question goes:

The product of 2 numbers is greater than 80 but less than 85. The sum of the 2 numbers is a multiple of 5. The difference between the 2 numbers is 8.
a) Find the product of the 2 numbers.
b) Find the 2 numbers.

If A is the bigger number and B is the second number than you know:
A * B > 80
A * B < 85
A + B ends in either a 5 or a 0
A - B or is either 8

Again, using square numbers (because A*B > 81 but less than <85) to create a reference point --> 9 * 9 = 81. Using the difference of 8 increase the first number, A, by 4 and decrease the second, B, by 4. This will give us A-->13 and B is 5. This doesn't work so try A-->14, B-->6. 14*6=84; 14+6=20; 14-6=8

The numbers are 14 and 6.
