Help help You are going to buy a total of 80 items

You have a budget of 250

2.95x+3.45y=250

1. Write your two equations below and solve the system of equations USING ANY METHOD

2. How many items are you able to purchase based upon the data you have collected thus far? You may need to round down since you will not be able to buy partial items!

Total number of item 1 (x) =

Total number of item 2 (y) =

multiple all that

step-by-step explanation:

27×17

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
