Answer:
[tex]23000 \times (1 + 0.02) ^{7} or \: 23000 \times (1.02)^{7} [/tex]
Step-by-step explanation:
As this is compound interest you would need to use this formula:
[tex] original \: value \times ( {1 + multiplier \: })^{time \:}[/tex]
And then you would need to subsite the values into this equation to make:
[tex]23000 \times (1 + 0.2)^{7} [/tex]
