Answer:
78
Step-by-step explanation:
angle ACD + angle DCB = 180 (Angles on straight line)
4x + 2 + 3x + 3 = 180
7x + 5 = 180
7x = 180-5
7x = 175
x = 175 / 7
x = 25
angle DCB = 3x +3 = 3*25 + 3 = 75 +3 = 78
First we have to figure out how much 3 bags cost using the total cost of $8.25
That means. we would do 8.25/3 and 8.25 divide by 3 equals 2.75.
Now we know that each bag costs approximately $2.75
All we have to do now is multiply 2.75 by 4 to get the cost for the total of 4 bags.
4 times 2.75 is exactly 11 dollars, if might change if theres tax.
But, the answer would be 4 bags costs $11.

Hello!
<u> Part A </u>
Peter can use the fact that 10% of 87 is 8.70 to find the amount he would save because 40% is just 4 times bigger than 10% so he can take 8.70 from to total of the coat 4 times to find out how much it cost.
<u> Part B </u>
Using the same method we know that 10% of 64 is 6.40 so we subtract that from the price of the coat 4 times to find out how much it cost
64 - 6.40 = 57.6
57.6 - 6.40 = 51.2
51.2 - 6.40 = 44.8
44.8 - 6.40 - 38.4
The price of the coat is $38.4

A soda costs $4. He spent a total of $19. Subtract 4 from 19
19 - 4 = 15
He bought 5 candy bars. Divide 15 with 5
15/5 = 3
Each candy bar costed $3.
hope this helps
