Christina will be retiring next month from her job after 35 years as a school bus driver. Over the last 35 years, Christina’s an
nual salary averaged $22,040. She expects to receive some money each month from Social Security and plans to take the rest of the money she needs to pay the monthly bills from savings. Each month her bills total to about $1,375. Assuming her annual Social Security benefit will be 42% of her salary average, how much will she need to take from savings each month to help pay the bills?
Given:
Annual salary average: $22,040
Annual Social security benefit: 42% of salary average
Monthly bill: $1,375
$22,040 x 42% = $9,256.80 per annum
$9,256.80 / 12 mos = $771.40 per month
$1,375 – 771.40 = $603.60
Since, Christina only receives $771.40 per month from her Social Security benefit, she has to take $603.60 from her savings each month to help pay her monthly bill of $1,375.

For this case, the first thing you should do is define a variable. We have then: t: temperature (degree Fahrenheit). We write then the inequation that adapts to the problem: t> = 451 Answer: an inequality that is true only for temperatures at which books spontaneously catch on fire is: t> = 451
