Answer:
Expression: 40x+35
40(10)+35= $435
Explanation:
There are 12 months, and we want to use the cellphone company for 10 months.
Let x represent months, and put 40 in front because that's the monthly charge for each month.
Next add 35 as your initial value to the expression.
When you go in the equation, 40 multiplied by 10 is 400.
400 plus 35 is 435.
So, $435 will be charged for 10 months of service.
