Ответ:
Buying 7 pumpkins and 3 watermelons, Astrid doesn't meet her two expectations.
Step-by-step explanation:
Let
P ----> the number of pumpkins and watermelons she can buy
W ----> the number of watermelons she can buy
we know that
Note Both inequalities are given in the problem
If Astrid buy 7 pumpkins and 3 watermelons
then
we have the ordered pair (7,3)
Remember that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities
For P=7, W=3
Verify Inequality A
substitute the value of P and the value of W
so
The ordered pair not satisfy the inequality A
Verify Inequality B
substitute the value of P and the value of W
so
The ordered satisfy the inequality B
therefore
Buying 7 pumpkins and 3 watermelons, Astrid doesn't meet her two expectations.
