The simple interest (Is)in a savings account varies jointly as the Principal (P) and the time (T). After 3 months, 8000 pesos deposit earned 100 pesos in interest. How much will a 10,000 pesos principal earn in 5 months?
\n" ); document.write( "This is about Variation. But this kind of variation is a joint variation. Its formula to solve it is y=kxz.
\n" ); document.write( ".
\n" ); document.write( "You are correct.
\n" ); document.write( "k = 1/240
\n" ); document.write( "AND
\n" ); document.write( "Is for 10,000 pesos in 5 months SHOULD be bigger.
\n" ); document.write( ".
\n" ); document.write( "How much will a 10,000 pesos principal earn in 5 months?
\n" ); document.write( "Is = (1/240)PT
\n" ); document.write( "Is = (1/240)(10000)(5)
\n" ); document.write( "Is = (1/24)(1000)(5)
\n" ); document.write( "Is = (1/24)(5000)
\n" ); document.write( "Is = 5000/24
\n" ); document.write( "Is = 208.33 pesos\r
\n" ); document.write( "
\n" ); document.write( "
