Answer: $34.32
Step-by-step explanation: We first calculate the price of the dress that was on sale. 30% of 35 is 35/10 x3. This is equal to 3.5x3 which is 7+3.5 = 10.5 We subtract this from 35 to get $24.5. So, the dress cost $24.5. Next 1/2 of 17 is 8.5. In total, the items cost $24.5+$8.5 = $33. Then, there is a 4% sales tax we have to add on to 33. 1% of 33 is 33/100 which is 0.33. This time 4 is 1.32. 33+1.32 is 34.32.
To find the inverse, turn the equation into x=4y-7 and solve for y. The inverse would be y=1/4x+7/4, or f(x)=1/4x+7/4. I hope this helps!
I think the answer is B but i could be wrong
Answer: changed by $48
Step-by-step explanation: 6 times $4 = $24 + $4 times 6 = $24 total= $48
Also $4 times 12 = $48
It would show the average time spent on the homework.
And the average distance between the mean and the lowest and highest numbers in the data.
