I do not know the decimal, but I know the ratio. 7/50. I am not positive about my answer as a decimal but I think it is 7.50.
Answer: instead of X put 5 and instead of y put 2
5+6(2)
5+12= 17
I don't know what the question is, but I may be able to help a little. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
First divide the new amount (7.28) by the original amount (7) and then times by 100
7.28 / 7 x 100 = 104
This tells us that 7.28 is 104% of 7
Minus this by 100 to get the sales tax rate:
104 - 100 = 4%
You could also subtract 7.28 by 7 first, then divide that by 7 and then multiply by 100:
7.28 - 7 = 0.28
0.28 / 7 x 100 = 4%
Answer:
A) each donut costs $0.65
B) the price for 1 and 1/2 dozen of donuts (18 donuts) is $11.70
Step-by-step explanation:
For a you have to divide $7.80 by 12 (since its a dozen) and thats how you get $0.65
For b you have to multiply the price of each donut ($0.65) by the 1 and 1/2 dozen (18 donuts) and thats how you get $11.70
