Answer 1

To compare the amount of money in each account, we need to simplify the expressions and compare the values.

For Sama's account:
Sama = $43⋅4−4(42)−5
= $43⋅4−169−5
= $172−169−5
= $3−5
= -$2

For Jimena's account:
Jimena = $3⋅(38)2(32)3 ⋅ 30
= $3⋅144⋅27⋅30
= $116,640

Comparing the values, we can see that Jimena has the most money in her account. Therefore, the answer is:

D) Jimena
