A cell phone company recently noticed a 30% sales decrease in the month of July compared to June. Let n represent June's sales. If y represents July's sales, which equation can be used to determine the sales in July? A. n=y-0.30y

B. y=n-0.30n

C. y=n+0.30n

D. y=n-0.30

4+2=-2. 1+2=3. y=-2/3x+b. 2=4/3+b. 2/3=b. the answer is y= -2/3x+2/3

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
