Answer:
The highest possible price of a sweater is $28.33
Step-by-step explanation:
We already know that price
of jeans is $35.Let's say Mrs.Smith buys 3 sweaters for
dollars each, and since her budget is $120 we have the inequality:

Therefore

Thus the maximum price of a sweater is $28.33
The rate of change of the linear function represented by the table is 3
<h3>Rate of change of a function</h3>
The rate of change of a function is also known as the slope of a function. The equation for calculating the slope is expressed as:
Slope = y2-y1/x2-x1
using the coordinates from the table (-2, -13) and (-1, -10)
Substitute
Slope = -10-(-13)/-1-(-2)
Slope = -10+13/-1+2
Slope =3
Hence the rate of change of the linear function represented by the table is 3
