Answer:

Part a) The estimate cost is about $9

Part b) The exact cost is $9.69

Step-by-step explanation:

we know that

Annie bought 3/4 kg of cocoa powder, which cost $12.92 per kg

Part a

To find the estimate cost round the numbers and multiply

we have

\$12.92=\$12 -----> round down

so

\frac{3}{4}(12)=\$9

Part b

To find the exact amount she had to pay, multiply 3/4 by $12.92

so

\frac{3}{4}(12.92)=\$9.69 ----> exact value

Answer:

Estimated cost; $9

Exact amount; $9.69

Step-by-step explanation:

We are told that ​Annie bought 3/4 kg of cocoa powder, which cost $12.92 per kg.

a.

We are required to estimate the cost of the 3/4 kg of cocoa powder given that 1 kg costs 12.92

We can round down the cost of a kg to obtain $12 per kg. Therefore, 3/4 of a kg will cost approximately;

(3/4) of 12

= (3/4)*12 = $9

Thus the estimated cost is $9

b.

We are required to determine the the exact amount she had to pay for the 3/4 kg of cocoa powder;

1 kg cost 12.92

3/4 of a kg will cost;

(3/4) of 12.92

= (3/4) * 12.92

Using a calculator we have;

9.69

Therefore, the exact amount paid was $9.69
