Answer:
$136.50
Step-by-step explanation:
100 - 12 = 88% (How much percentage of money the student left)
88% = 120.12
1% = 120.12 ÷ 88 = 1.365
Before buying the book, the student had 100%
100% = 1.365 x 100 = 136.50
Choice 1
Choice 1 and 3 shows parallel, choice 2 and 4 shows perpendicular. So cross out choices 2 and 4. We’re left with choices 1 and 3. I would go with choice 1 since choice 3 shows RAY A is parallel to RAY B, which isn’t true, they’re not parallel.
