Question

Zach invested $50 and tripled his money in 2 years. Kayla also invested $50 and after 2 years the amount was equal to 50 to the third power. Who had more money after 2 years?

Answer 1

Kayla had more money after 2 years

Explanation:

Data provided in the question:

Amount invested by Zack = $50

Amount after 2 years = triple money

Thus,

The amount with the Zack after 2 years = 3 × $50

= $150

Now,

The Amount invested by Kayla = $50

The Amount after 2 years with Kayla = 50 to the third power

= 50³

= 50 × 50 × 50

= $125,000

since,

$125,000 > $150

Hence,

Kayla had more money after 2 years
