Let's say my employee sells 10 phones and attaches insurance to 4 of them, we know the attach rate is 40%. I'm trying to figure out what the equation would be if I wanted to get that number to 60%, how many phones I'd have to have him consecutively sell to hit that goal.

Thanks!

You'd have to sell 15 phones to hit that goal.

Cross multiply;



60 = 4x

x = 15

unless i'm confused there is no answer.

people have a 40% chance to attach insurance, which will remain no matter how many phones u sell.

unless you meant "how many phones do i need to sell to sell 6 insurance plans"

you need to change your insurance plan to increase the attachment rate, not the # of phones sold.

If attachment rate and phones sold are positively correlated with one another, post #1 is correct. However, economically speaking, poster #2 is correct.
For the sake of your business it will be most profitable to re-evaluate your business model with respect to the insurance attachment (i.e. make it more appealing for customers to buy an insurance for their phones).

/e That's poster 2 and 3, apparently.

Vincenzo is right but answer is lacking a bit of detail.

You'd have to sell 5 more phones consecutively with insurance.

You would then have 9 phones out of 15 sold with insurance. 60%
