A candy bar and a piece of bubble gum together cost $1.10. The candy bar costs a dollar more than the bubble gum. How much does the candy bar cost, in dollars?

$1.05

Step-by-step explanation:

Say the price of a piece of bubble gum is x. This means that we can represent our scenario with the equation (x+1)+x=1.10, with (x+1) representing the price of a candy bar. We can then solve from there.

(x+1)+x=1.10 - Given

2x+1=1.10 - Simplify

2x=0.10 - Subtract From Both Sides (sorry, I forgot the name of this property)

x=0.05 - Divide From Both Sides

So now we have the price of the piece of bubble gum, but we want the cost of the candy bar. Fortunately, we know it costs one dollar more than the piece of bubble gum, so just do 0.05 + 1. This means our candy bar costs $1.05.

y=3n + 1

this is wrong because it says the second number is one less and i added one instead
