8.50 x 38 = 323 for the first week
46-40= 6
40 x 8.50 = 340
8.5 x 1.5 = 12.75
12.75 x 6 = 76.50
340 + 76.50 = 416.50 for the second week

Answer:
-x² + 16x - 60
Step-by-step explanation:
Given expression:
Step 1. <u>Insert</u> brackets to isolate the "-" from the (x - 8)².
⇒ -(x - 8)² + 4
⇒ -[(x - 8)²] + 4
Step 2. <u>Use</u> the formula (a - b)² = a² - 2ab + b²
⇒ -[(x - 8)²] + 4
⇒ -[x² - 2(x)(8) + 8²] + 4
Step 3. <u>Open</u> the parenthesis
⇒ -[x² - 2(x)(8) + 8²] + 4
⇒ -x² + 2(x)(8) - 8² + 4
Step 4. <u>Simplify</u> as needed
⇒ -x² + 16(x) - 64 + 4
⇒ -x² + 16x - 60
