b. You notice that the shirt is on sale for %30 off. How does this change the inequality?
c. Do you have enough money to buy the shirt that is on sale and a pair of pants that cost $23? Explain.
Answer:
x ≤ 21
x ≤ 25.2
Yes
Explanation:
Cost of shirt = $14
Total Amount to spend ≤ $35
After shirt purchase :
Let amount left = x
x + 14 ≤ 35
x ≤ 35 - 14
x ≤ $21
B.) discount on shirt sale = 30%
(100% - 30%) of $14 = 0.7 * $14 = $9.8
x ≤ 35 - 9.8
x ≤ 25.2
C.)
Cost of Jean = 23
25.2 > 23
Hence, there is enough money
