Answer:
$1350
Step-by-step explanation:
5% of 1000 is 50
50x7 is 350
1000+350=1350
What we want to do first is isolate the variable. To do this we need to multiply each side by 5 to remove the fraction
5 * 5 = 5*
w
Simplify the right side
5 *

Now simplify the left side
5 * 5 = 25
Then we get...
25 = w
There's your answer!
