Answer:
<u>After July, Ana's monthly salary was $1920</u>
Step-by-step explanation:
In May, Ana's monthly salary was $2000. During the next month, the salary increased by 20%, or (0.2)(2000)
So, in June, Ana's monthly salary was $2400. During the next month, the salary decreased by 20%, or (0.2)(2000)
Therefore, after the two changes, Ana's monthly salary was <u>$1920</u>
Answer:
87.5
Step-by-step explanation:
100 - (12.5% × 100)
100 - 12.5% × 100
(1 - 12.5%) × 100
(100% - 12.5%) × 100
87.5% × 100
87.5 ÷ 100 × 100
87.5 × 100 ÷ 100
8,750 ÷ 100 = 87.5
This should be the equation:
n + 4/3n + 5/3n = 90
You would divide negative 3 (-3) from both sides to keep the c by itself. When you divide a positive by a negative it becomes negative.
Dividing 15 by -3 would equal -5, so c = -5
