19.98 = x + x(1.6)
19.98 = 1.6x + x
19.98 = 2.6x
x = 7.68
x(1.6) = 12.29
The cost is $7.68 and the markup is $12.29. (Approximate due to rounding)
Hope this helps!! :)
Simplify negative 7 and 1 over 8 − negative 9 and 1 over 2.
The answer is 2 and 3/8.
To find this we need to look at the entire equation.
-7 1/8 - -9 1/2
When we have two negatives like this, we need to turn it into an addition sign.
-7 1/8 + 9 1/2
Now we need to give them common denominators
-7 1/8 + 9 4/8
Now we can simply add the two parts
2 3/8
