Answer:
domain = ( -infinity, infinity) = all real numbers
range = ( -1, infinity)
Answer:
Step-by-step explanation:
2500 - 12%
12% of 2500 = 300
2500 - 300 = 2200
12% of 2200 = 264
2200-264=1936
Repeat another 4 times
Cost of lack increased by 30%
new cost of lack will be = 100% + 30% = 130%
We are given that new cost = £65
Thus 130% of original cost = 65
100% of original cost = 65 × 100/130 = £50
Thus original price was £50
You have to make a proportion:
12+x/8=8/x
Then cross multiply to solve for x
