B
to calculate percent increase use
× 100%
increase = $650 - $525 = $125
percent increase = × 100% = 24% → B
For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.
Write what you know in an equation: 27=30%•X. Divide 27 by .30 to get X alone: 27/.30=90. 27 is 30% of 90 :)
Answer:
c
Step-by-step explanation:
the domain is every possible input value and the range is every possible output value. since the outputs are all positive, the range is equal to all real numbers. and since the graph starts at 1,000, the domain is greater than or equal to 1,000
