Please help me with this problem! i need it answered asap! (will give brainliest)

Use substitution to solve the system of equations.
y + x = 3
y = 1.5x + 1

x = .8

y = 2.2

Step-by-step explanation:

We can solve by substituting y = 1.5x + 1 into the first equation!

Next, we need to substitute the value of 4-fifths into an equation! I will choose the second equation!

When converted into decimal form, y and x should look like this:

4/5 = .8

11/5 = 2.2

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
