Ronny is selling coffee for $5. So far he earned $350. Ronny needs to earn more than $510 in order to meet his goal. How many mugs, x, does Ronny need to sell in order to reach his goal?

He needs to sell 32 more cups of coffee to reach his goal.

Step-by-step explanation:

510-250=160

160/5=32

x = 32

He had already sold 70 cups, so altogether, from the beginning, he would have had to sold 102 cups.  

-6 is the correct option from the above given options

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
