Answer:
34 pounds
Step-by-step explanation:
hi again!
so if three students have 10.2 to wash, we can find how many pounds the 3 students have in total by multiplying 10.2*3, because that is the same as doing 10.2+10.2+10.2. this gives us a result of 30.6 points for the three students.
now if the fourth student has 3.4 pounds, we just add that to 30.6
thus we have 30.6+3.4 which equals your answer, 34.
In order to calculate the equivalent discount, consider the principle number is 100,
Then, 100 - 100 * 0.20 = 100 - 20 = 80
Now, 80 - 80 * 0.15 = 80 - 12 = 68
So, Total discount would be: 100 - 68 = 32%
Hope this helps!
Before you can use the reason CPCTC, you need to show that two figures which usually are triangles to be congruent. After showing such, you can then say Corresponding parts of the two congruent figures are also congruent to each other.
