Question

Jessica pays a flat rate of $70 for her cell phone and is charged $0.05 for every text she sends. Jessica spends more than $80 on her phone bill each month. Which of the following describes the number of texts she sends?

a minimum of 200

a maximum of 200

fewer than 200

more than 200

Answer 1

she pays a flat/fixed rate, a static value, of $70
and 5cents for each sms text

she spends MORE THAN $80 monthly

how many sms text she sends? well, we dunno, let's say "t"
since each is 5cents or $0.05
then she spends in sms text alone $0.05t

so we could say that her static/flat charge of $70 PLUS her sms text charges are MORE THAN $80

that is
$70 + $0.05t > $80
70 + 0.05t > 80

solve for "t"
