Make the number 693,000 instead of 69,300. The answer would be 86,625.
Hope this helped, I wasn’t to sure on what you were asking though.
It would cost $105 because if you do 13+13+13= 39
22+22+22= 66
66+39= 105.
Yes, Lord Vader !
2/3 x + 5 = 1/2
Multiply each side by 2 : 4/3 x + 10 = 1
Multiply each side by 3 : 4 x + 30 = 3 <== equivalent equation
without fractions
Subtract 30 from each side: 4x = -27
Divide each side by 4 : x = -27/4 = -6.75
Well, if the notebooks cost x, then you know that
3x + 45.87 = 60.54
right? so, solve for x. 60.54 - 45.87 = 14.67
Divide the difference by 3.
