2.)

Compute the total cost per year of the following pair of expenses. Then complete the​ sentence: On an annual​ basis, the first set of expenses is​ _______% of the second set of expenses.

Sheryl spends​$10 every week on cigarettes and spends ​$20 a month on dry cleaning.

On an annual​ basis, the money spent on cigarettes is what ​% of the money spent on dry cleaning.

Answer 1

1) Total cost per year = (Monthly cell phone bill * 12 Months) + yearly spending on health insurance

= ( $87 per​ month * 12 Months) + $168

= $1,044 + $168

= $1,212

Total cost per year = $1,212

The first set of expenses ( cell phone bill)% is of the second set of expenses (spending on health insurance )

= $1,044 / $168 *100

= 621.43%

So On an annual​ basis, the first set of expenses is​ 621.43 % of the second set of expenses.

2) Total cost per year =

(Weekly spending on cigarettes * 52 weeks) + (Monthly spending on dry cleaning * 12 months)

= ( $10 per​ Week * 52 weeks) + ($20 * 12 months)

= $520 + $ 240

= $760

Total cost per year = $760

The first set of expenses ( spending on cigarettes ) % is of the second set of expenses (spending on dry cleaning )

= $520 / $240*100

= 216.67%

So On an annual​ basis, the first set of expenses is​ 216.67% of the second set of expenses.
