The best thing to do is to find what 1% is, and you can do this by dividing 150 by 100.
150/100= 1.5
As you're looking for 6.5%, you've got to multiply 1.5 by 6.5
1.5*6.5= 9.75
You've then got to add 9.75 and 150 together
150+9.75= $159.75
Therefore, after the sales tax, the cost of the necklace is $159.75
Hope this helps :)
-12x/-4= -27
(-4)-12x/-4 it will cancel the 4 but you gotta multiply on the other side by 4 too
now have -12x =108
-12x=108
divide 108 by -12x which x=-9
You should do 24.30/9 which equals $2.70
-9, -8, -7, etc. With positive numbers, greater value is determined by raising the number. However, with negatives, the smaller the number it is (aka the closer it is to 0), the greater value it has. This causes numbers like -1 to be greater than -10. Hope this helps :)
