I think it’s -6 but I would check with someone else too lol
9.75+5.29+7.13=22.08
Miguel spent about $22.08 in the toy store
The approximate equation is n = (ln 6)/10 and approximate value is n = 0.179.
<h3>What is Exponential equation?</h3>
In mathematics, an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.
Here, given equation; (we are using n in place of t)
-5.e¹⁰ⁿ = -30
On dividing -5 both sides, we get
-5.e¹⁰ⁿ/-5 = -30/-5
e¹⁰ⁿ = 6
Taking 'ln' on both side, we get
10n = ln 6
n = (ln 6)/10
n = 1.791759/10
n = 0.179
Thus, the approximate equation is n = (ln 6)/10 and approximate value is n = 0.179.

I think the equation is formed wrong, as there is no point in having x-4=x-2 twice.
It has no solution.
Answer:
Danny
Step-by-step explanation:
Its quite obvious really.
Multiply Danny's charges by 2
20 x 2
Thats $40 for 4 hours unlike Martins $68 for 4 hours.
If you wanna go further,
Minus Martins charges with Dannys
68 - 40
Thats a $28 gap.
