Answer:
−
-3^3/3250
Step-by-step explanation:
N + n + 3 + 2n = (sum of age)
First change the problem and add 1 in front of the variables (n)
1n + 1n + 3 + 2n = (sum of age)
Next add the like terms which are 1n, 1n, and 2n
1n + 1n = 2n
2n + 2n = 4n
Now 3 is left by itself add it to the problem
4n + 3
SIMPLIFIED EXPRESSION IS 4n + 3
A. Total amount raised, A, equals 92 sponsors times number of kilometers, n, times $1 per kilometer, plus additional donations, d.
b. Yes. Write an equation based on the verbal model: A = 92n +d. Substitute the information from the problem into the equation and solve for d: 842 = 92(8) + d. The amount of money from additional donations is $106.
