On an annual​ basis, the money spent on lottery tickets is       ​% of the money spent to buy food. ​(Round to the nearest percent as​needed.)

Answer:

Maria's Spending

On an annual​basis, the first set of expenses is​ ____55.39___% of the second set of expenses.  Maria spends ​$17 on lottery tickets every week and spends $133 per month on food. On an annual​ basis, the money spent on lottery tickets is    55.39   ​% of the money spent to buy food.

Explanation:

Maria spends ​$17 on lottery tickets every week

Therefore, every 4-week month, she spends $68 ($17 * 4) on lottery tickets

Normally, a year = 52 weeks.

Annually, Maria spends $884 ($17 * 52) on lottery tickets

Also

Maria spends $133 per month on food.

Normally, a year = 12 months.

Annually, she spends $1,596 ($133 x 12) on food

Ratio of Lottery tickets to Food annually:

= $884 : $1,596

= $884/$1,596

= 55.39%

or

0.5539 : 1

b) What is done here is to convert to each cost to its annual equivalent.  The cost of Lottery tickets was converted from per week basis to per annum.  The cost of food was converted from per month basis to per annum.  These conversions make the two variables comparable, since they have been reduced to similar standards of measurement.
