(pre-algebra) If Thomas has $1000 for a vacation, his plane ticket costs $348.25, and he will be there for 5.5 days, how much money can he spend each day? I need a inequality, you don't need to give me the answer to the inequality, I can do that. (Also don't do one like this: $1000 - $348.25 = $651.75 ÷ 5.5 = $118.5, It's not asking for that.)

answer: y=4000x+14000

step-by-step explanation:

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

your answer   is c
