Jessica's cell phone charges her a monthly fee plus a charge for each message she sends. how much does jessica pay for each text message? show work number of text messages[50] cost{$35.00} number of text messages[75] cost[$35.75]

Step-by-step explanation: since the question is about the unit price of each text message

For the first month it is $35/50= $0.7per text message

The second month it's $35.75/75=$0.47 per text message

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
