Answer:
No, her answer is unreasonable because 0.2 * 6 = 1.2
Step-by-step explanation:
Here in this question, we are trying to use an approximation to see if what was said to be the result of a calculation is reasonable as an answer.
Looking at her division, 2.76/6 = 0.19
To the nearest tenth , 0.19 is same as 0.2, now multiplying 0.2 by 6, what we have is 1.2 ( of which even 0.19 * 6 is expected to be less than this). we can see that this value is quite far from our expected answer of 2.76 which makes the answer an unreasonable one
Thus, the division 2.76/6 = 0.19 is not a reasonable answer
Answer:
1/3 is the y-intercept of the function
5 x 3 = 15
15 x 12 = 180

Answer:
$22.47
Step-by-step explanation:
Shirts are on sale for 30% discount
The original price of one shirt is $15
Discount = percentage discount/100 × original price = 
× $15 = $4.5
The selling price of one shirt is therefore;
$15 - $4.5 = $10.5
For two shirts, the selling price is 2 × $10.5 = $21
Tax = Percentage tax/100 × selling price = 
× $21 = $1.47
The total cost of these two shirts at sale price = $21 + $1.47 = $22.47
