alukav5142 [94]

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

Marissa has twice as much money as Frank. Christina has $20 more than Marissa. If Christina has $100, how much money does Frank

qwelly [4]

Answer:

a. Take a grid that shows represents the amount of money Frank has,

Say F,

( shown below ),

b. Since, Marissa has twice as much money as Frank,

So, the amount Marissa has = 2F

If M represents the amount Marissa has,

M = 2F

c. Now, Christina has $20 more than Marissa,

Add 20 to the grid M

d. The below diagram provides enough information to determine the value of the variable m

e. The amount Christina has = M + 20 = 2F + 20

According to the question,

2F + 20 = 100

2F = 80

F = 40

Hence, the amount frank has = $ 40,

Amount Marissa has = 2(40) = $ 80,

It wants you to find how much money you will spend a year at each separate gym. That way you can find out which one is cheaper. Once you’ve done that, you need to find how many days it would take for both gym’s cost to be the same after so many days.
