Answer:
10% discount
Step-by-step explanation:
If you take 369 divided by 410 it gives you 0.9 which is equal to 90% which then leads us to realized that if 369 is 90% of 410 then the discount would have to be 10%
Answer:
y= -4
Step-by-step explanation:
x+y=42. We know that x plus y equals 42.
x=2y . We also know that x equals twice y.
2y+y=42. Since we know that x=2y, we're going to replace x with 2y from the original equation, simplified would be 3y=42.
y=14. 3y=42 simplified is y=14, this is because we divided both sides by 3 (since 3 and 42 are both divisible by 3) (btw divisible by 3 simply means that it can be divided by 3)
x+14=42. Now that we know what y equals, let's replace y with 14 from the original equation.
x=28. Now that we know that x=28 and y=14, we know that y is always x/2.
When x=-8, we divide it by 2 and get, -4.
Not absolutely positive as this was all mental math, but hope this helps! :)
First day = 10 +8
=18
second day = 8+8
=16
3rd=16
4th= 16
5th=16
6th=16
16+16+16+16+16+18
=80+18
=98
I think the answer will be C
