Question

The table shows how much money Earl's grandmother gave him each birthday.

Age Birthday Money
5 15
8 24
10 30
16 ?


At this rate, how much money should Earl receive from his grandmother when he turns 16?
$36
$48
$51
$55

Answer 1

$48

3x16 = 48

It is just multiplying the age by 3

Answer 2

To determine how much money Earl should receive from his grandmother when he turns 16, we can observe the pattern in the given table. The birthday money increases as Earl gets older. Let's examine the differences between consecutive ages:

Age 8 - Age 5: $24 - $15 = $9
Age 10 - Age 8: $30 - $24 = $6

Based on this pattern, we can assume that the increase in birthday money decreases by $3 between each two-year gap. Therefore, for the difference between Age 16 and Age 10, we subtract $3 four times:

$30 - $3 - $3 - $3 - $3 = $30 - $12 = $18

So, the amount of money Earl should receive from his grandmother when he turns 16 is:

$30 + $18 = $48

Therefore, Earl should receive $48 from his grandmother on his 16th birthday. The correct answer is $48.
