3 multiple choice 1 point solve the formula for the indicated variable. a = p(1 + rt) for r r = -\\frac{a + p}{tp} r = \\frac{a - p}{tp} r = \\frac{a + p}{tp} r = \\frac{p - a}{tp}

3 multiple choice 1 point solve the formula for the indicated variable. a = p(1 + rt) for r r = -\\frac{a + p}{tp} r = \\frac{a - p}{tp} r = \\frac{a + p}{tp} r = \\frac{p - a}{tp}

Answer

Explanation:

Step1: Expand the right - hand side

$A = P(1 + rt)=P+Prt$

Step2: Isolate the term with $r$

$A - P=Prt$

Step3: Solve for $r$

$r=\frac{A - P}{tP}$

Answer:

$r=\frac{A - P}{tP}$, so the correct option is $r=\frac{A - P}{tP}$ (the second option in the multiple - choice list).
