Answer: 1/4

Step-by-step explanation:

In a group of 84 kids 3/7 brought their lunches. This means that the number of kids that bought their lunches will be 3/7 ×total number of kids

= 3/7 × 84 = 36 kids

Of those who bought their lunches 9 got a slice of pizza. This means that 9 kids out of 36 got a slice of pizza.

Fraction of the students who bought their lunches and got a slice of pizza will be the number of students who bought their lunches and got a slice of pizza / the total number of students that bought their lunch. This becomes

9/36 = 1/4

Leo's bank balances at the end of months 1, 2, and 3 are $1500, $1530, and $1560.60,
grandymaker [24]

Leo's balance after 9 months will be: $1757.49

Step-by-step explanation:

It is given that the balances follow a geometric sequence

First of all, we have to find the common ratio

Here

a_1 = 1500\\a_2 = 1530\\a_3 = 1560.60

Common ratio is:

r = \frac{a_2}{a_1} = \frac{1530}{1500} = 1.02\\r = \frac{a_3}{a_2} = \frac{1560.60}{1530} = 1.02

So r = 1.02

The general form for geometric sequence is:

a_n = a_1r^{n-1}

Putting the first term and r

a_n = 1500 . (1.02)^{n-1}

To find the 9th month's balance

Putting n=9

a_9 = 1500 . (1.02)^{9-1}\\= 1500.(1.02)^8\\=1757.4890

Rounding off to nearest hundredth

$1757.49

Hence,

Leo's balance after 9 months will be: $1757.49
