Answer:
The correct option is :
Inequality 1 is incorrect; it should be g ≤ 80.
Step-by-step explanation:
Let Kyle's age be = k
Let the grandmother's age be = g
Kyle says his grandmother is not more than 80 years old. This means \(g\leq 80\)
He says his grandmother’s age is, at most, 3 years less than 3 times his own age. This means \(g\leq 3k-3\)
Jane wrote:
Inequality 1: \(g>80\)
Inequality 2: \(g\leq 3k- 3\)
Jane wrote the 1st inequality wrong. As she has shown that the grandmother's age is greater than 80, which is not.
So, the correct option is :
Inequality 1 is incorrect; it should be g ≤ 80.
