Solve my question " the sum of digits of two digit number is 8.if 27 is subtracted from the number, the ones and tens digit of the new number so formed become equal. find thr number."

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

The answer is that the rate of change is $50 per 1 monthhope this ; )
