4.5

Maybe I’m missing something, but from how I understand this question 4.5 is the only possible answer.

- 4.5 doubles to 9
- subtract 1 from 9 to get 8
- square 8 for the result of 64

(This is just my logic, but maybe my thought process can help you!)

Marco wants to buy a new smartphone that costs $495, with some additional accessories. He has already saved $75. Write and solve
antoniya [11.8K]

Marco needs to save a minimum of $420 more to buy a smartphone.

<u>Explanation:</u>

Cost of a smartphone = $495

Savings = $75

Least amount of money, m that needs to be saved = ?

Additional savings, m = Total - initial savings

                              m = $495 - $75

                              m = $420

The inequality equation would be 75 + m ≥ 495

Therefore, Marco needs to save a minimum of $420 more to buy a smartphone.
