Julie is throwing a surprise birthday party for her friend. She wants to spend no more than $35.00 on decorations. At a local party store, she can buy helium-filled balloons for $2.50 each and rolls of streamers for $3.50 per roll. Let x represent the number of balloons purchased and y be the number of rolls of streamers. the inequality 2.50x +3.50y<=35.00. determine how many of each type of decoration she can buy. If Julie wants to buy 6 balloons, how many rolls of streamers can she buy without going over budget?

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

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
