In 2014, there were 22 million americans
diagnosed with diabetes. this number of cases repre-
sents an increase of 300% over the number of cases
in 1980. how many cases of diabetes were there in
1980?

5.5 millions

Step-by-step explanation:

If the price is increased by 300% lets say the starting price was 100$, then it becomes 400$, So to get the starting price You have to divide it by 4 not 3. In this case People who got diabetes are 22/4=5.5 million people

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
