On an annual basis, the money spent on lottery tickets is % of the money spent to buy food. (Round to the nearest percent asneeded.)
Answer:
Maria's Spending
On an annualbasis, 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.
