3(6m)+m *Distribute
18m+m *Simplify/Add
19m
19m=19m :)
2(x-3)5x = 5(2x6)
2(x-3)5x = 60
2x -6 x 5x = 60
2x -30x = 60
-28x = 60
28x = -60
x = -15/7
Not sure if I'm correct, but hope it helped
Answer:
280
Step-by-step explanation:
Answer:
- $425
- i. $595 ii. $476
- First ski
Step-by-step explanation:
1. The first ski was valued at $850 but was then given a 50% discount. The sales price will therefore be:
= 850 * ( 1 - 50%)
= 850 * 50%
= $425
2. The first one was first discounted by 30% so the sales price was:
= 850 * ( 1 - 30%)
= 850 * 70%
= $595
It was then marked down by a further 20%:
= 595 * ( 1 + 20%)
= $476
<em>3. The first ski is a better option because the discount makes it cheaper than the second ski even after the second ski had been discounted twice. </em>
