?
PLEASE HELP ASAP
Answers
Answer:
20%
Step-by-step explanation:
So, I would set this up as a proportion-
72 x
90 100
Cross multiply-
100 x 72 = 7200
Divide-
7200/90 = 80
Subtract-
100 - 80 = 20
So, it is a 20% decrease

Alex is a stockbroker. Earns % commission each week. Last week, sold $ worth of stocks. How much did he make last week in commission? If he averages that same amount each week, how much did he make in commission in 2011?
Answers
Answer:
a. $896
b. $46,592
Step-by-step explanation:
a. Alex earns 14% of the amount of stock he sells in a week.
The week before he sold $6,400. This means that his earnings in commission are:
= 14% * 6,400
= $896
b. Commission for the year:
If he makes $896 per week, there are 52 weeks in a year. Per year he would make:
= 896 * 52
= $46,592
In 2010, there were 12.4 million citizens of a certain country diagnosed with diabetes. This number of cases represents an increase of about 396% over the number of cases in 1973. How many cases of diabetes were there in 1973?
Answers
Answer:
3,131,313
Step-by-step explanation:
Let X represent the number of cases with diabetes in 1973.
An increase of 396% in diabetes cases in 1973 would be;
12.4 million = 396/100 × X
12.4 million = 396X/100
Cross multiply
12.4 million × 100 = 396X
X = [(12.4 million × 100) / 396]
X = 3,131,313
Therefore, the number of diabetes cases in 1973 is 3,131,313 cases
