You deposit $300 in an account earning 4.5% simple interest for
12 years. How much will your investment be worth at the end of
12 years?

$462

Step-by-step explanation:

principal(p)=$300

Rate(r)=4.5%

time(t)=12years

Simple interest=(pxrxt) ➗ 100

Simple interest=(300x4.5x12) ➗ 100

Simple interest=16200 ➗ 100

Simple interest=162

Total amount=p + simple interest

Total amount=300+162

Total amount=$462

addition

step-by-step explanation:

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
