2(n+9)=6 divide both sides by 2
n+9=3 subtract 9 from both sides
n=-6
check
2(-6+9)=6
2(3)=6
6=6

Answer:
(a) C = 0.29<em>t</em> + 2.50
(b) 5
Step-by-step explanation:
The variables are defined as follows:
<em>t</em> = the number of toppings
<em>C</em> = total cost for ice cream
It is provided that:
- An ice cream with no toppings is $2.50.
- Every topping is priced at $0.29 each.
(a)
The algebraic equation to find the total cost for ice cream depending on the number of toppings is:
C = 0.29<em>t</em> + 2.50
(b)
Compute the number of toppings Mr. Torrance can buy if he wants to spend only $4.00 on it as follows:
C = 0.29<em>t</em> + 2.50
4.00 = 0.29<em>t</em> + 2.50
0.29<em>t</em> = 4.00 - 2.50
0.29<em>t</em> = 1.50
<em>t</em> = 5.1724
<em>t</em> ≈ 5
Thus, Mr. Torrance can buy 5 toppings.
