Answer:

The equation that represents the best estimate is

B. <u>$0.40 × 30 = $12 </u>

The actual total cost of all the bolts is

<u>$12.54</u>

Explanation:

From the question given above, we know that

total bolts = 33

cost of 1 bolt = $0.38 approximating the values,

Total bolts = 33 ≅ 30

Cost of 1 bolt = $0.38 ≅ $0.40

Therefore,

Cost of all bolts = Total bolts x cost price for 1 bolts

= 33 x $0.38 = $12.54 ≅ $12.00
