Answer:
200
Step-by-step explanation:
If you do 15/.075 gives you 200 meaning 7.5% of 200 is 15.
You can check your answer by doing 200 × .075 which does give you 15
Two factors of -5 are -5 and 1. -5 and 1 make a sum of -4, so the equation can be factored into (x-5)(x+1)=0
x-5=0 or x+1=0
x=5 or x=-1
Answer:
27.9 dollars
Step-by-step explanation:
2.70= 15 percent
2.70x2=5.4=30 percent
5.4+2.70=8.1=45 percent
8.1x2=16.2=95 percent
95 percent + 15 percent=18.9
18.9=105 percent
in order to subtract 5 percent we need to find 5 percent by dividing 2.70 by 3
which = .9
18.9+9=27.9
100 percent is 27.9 dollars
