How do you increment a number via input in multiple conditions?

Shibitto (27)
I'm trying to increment the input to take the requested input and have that output the unknown value in one condition, then carry it to the next condition. Doubt a while loop, or for loop is necessary. I think my variable assignments are wrong, i've tried a for loop, a stod, I was going to use a vector.

Im trying to keep it simple. Every time I do raise the input by 0.70, it ends up being a $1.70, so removing the input from the user it doesn't allow me to increment. I cant use two different inputs but one.

I must always remember Simplicity is key.

don't understand what you're asking.
please rephrase, simplify and exemplify.

also, ¿do you know about else?

You just have to adjusted the values for diskette it doesnt match what you're asking the user to input
