$0.29 * 3 = $0.87
$0.98 * 2 = $1.96
$1.39 * 1 = $1.39
0.87 + 1.96 = 2.83
2.83 + 1.39 = 4.22
10.00 - 4.22 = $5.78
she will get $5.78 back!
Answer:
Step-by-step explanation:
We have given two function f(x) and g(x)
We need to operate 
Substituting the values in the above format we will get
after opening the parenthesis we will get
We will get after simplification the above expression
Addition of these two functions give us a quadratic expression means an expression with degree or highest exponent two.

In 386750.36 years the Carbon - 14 will be 20 g in the substance
Step-by-step explanation:
Here A = 20 g
The given equation is,
A= 25e - 0.000124t
We need to find the value of t
20 = 25e - 0.000124t
20 - 25e = - 0.000124t
25e - 20 = 0.000124t
(25e - 20 ) / 0.000124 = t
t = (25e - 20) / 0.000124
t = (65.957 - 20) / 0.000124
t = 45.957 / 0.000124
t = 386750.36 years
