Let’s solve each problem step by step.

Problem 1: Solve: 5 + 9 × 3 – 8
We must follow the order of operations (PEMDAS/BODMAS):
→ Multiplication first, then addition and subtraction from left to right.
Step 1: Do multiplication → 9 × 3 = 27
Now expression becomes: 5 + 27 – 8
Step 2: Add 5 + 27 = 32
Then subtract 8 → 32 – 8 = 24
✔ Final answer for #1:
D. 24

Problem 2: Which is smallest: 9 × 6 -or- 8 × 7 -or- 5 × 11?
Calculate each:
- 9 × 6 = 54
- 8 × 7 = 56
- 5 × 11 = 55
So we have: 54, 56, 55 → smallest is
54, which is 9 × 6
✔ Final answer for #2:
A. 9 x 6

Problem 3: What is the vehicle’s speed when traveling 30 miles in 30 minutes?
Speed = distance ÷ time
But time must be in hours if we want mph (miles per hour).
30 minutes = 0.5 hours
So: 30 miles ÷ 0.5 hours =
60 mph
Also, 30 miles in 30 minutes means 1 mile per minute → that’s also correct.
Check options:
C. 60 mph → correct
D. a mile a minute → also correct
E. Both C) and D) are correct answers → YES!
✔ Final answer for #3:
E. Both C) and D) are correct answers

Problem 4: Sam’s Bakery makes 3000 donuts in 6 hours, while Annie bakes 4800 donuts per 10-hr day.
Find who is more efficient → compare donuts per hour.
Sam: 3000 ÷ 6 =
500 donuts/hour
Annie: 4800 ÷ 10 =
480 donuts/hour
So Sam makes 500 - 480 =
20 more donuts per hour than Annie.
Look at options:
C. Sam is more efficient by 20 donuts / hr. →
✔ Correct
Others:
A. Says Annie is more efficient — false
B. Talks about fewer hours — not relevant to efficiency rate
D. Says Annie is more efficient — false
E. Says same rate — false
✔ Final answer for #4:
C. Sam is more efficient by 20 donuts / hr.
