Answer:
a) $3.45
b) P(x) = 0.0003x -18
c) $3.00, A
Step-by-step explanation:
a) When the family income is $71,500, it exceeds $70,000 by ...
$71,500 -70,000 = $1500
Then the price of the child's lunch will be ...
$3.00 + 0.0003×1500 = $3.45
__
b) For family income in the given range, the price of a lunch will be ...
P(x) = 3.00 + 0.0003(x -70000) = 3.00 +0.0003x -21.00
P(x) = 0.0003x -18.00
__
c) P(70000) = 0.0003×70000 -18 = 3×7-18 = 3.00
The definition of P(x) in part (b) tells you the meaning of this. x=70,000 is the family's annual income; P(x) is the price of a lunch.
P(70,000) is the price of a lunch for a child whose family annual income is $70,000.

The equation that represents the given problem is (n-30) + n = 210. The correct option is the first option (n-30) + n = 210
<h3>Linear equation</h3>
From the question, we are to write an equation for the given problem
From the given information,
n = Tom's weight in pounds
If Jim weighs 30 pounds less than Tom
Then,
Jim weighs (n - 30)
Thus,
The sum of their weight is
(n-30) + n
∴ (n-30) + n = 210
Hence, the equation that represents the given problem is (n-30) + n = 210. The correct option is the first option (n-30) + n = 210
