Can someone me on 4a for 43 points.

Tierra's equation: 1.05 x 100 = 105. She will have $105 in her savings account
Cameron's equation. 100 + 0.005 x 100 = 100.5. She will have $100.5 in her savings account.
Justice's equation: 100 x 1.005 = 100.5. She will have $100.5 in her savings account.
The account either has $105.00 or $100.50. 

Hi there!

Based off of your problem there are three to solve:

Tierra's Equation: T = 1.05 × M
Cameron's Equation: T = M + 0.005 × M
Justice's Equation: T = M × (1 + 0.005)

Also according to your problem, the variables T & M are as follows:

T = total savings
M = initial amount of money put in

To solve Tierra's Equation plugin the number as follows:

T = 1.05 × $100

So 100 time 1.05 equals:

$105 = 1.05 × $100

To solve Cameron's Equation plugin the number as follows:

T = $100 + 0.005 × $100

So $100 plus 0.005 times $100 equals:

$100.5 = $100 + 0.005 × $100

To solve Justice's Equation plugin the number as follows:

T = $100 × (1 + 0.005)

So $100 times 1 plus 0.005 equals:

$100.5 = $100 × (1 + 0.005)

The total savings of them all are not the same.
