Substitue I=100 r=0.01 t=1/2 into the formula for simple intrest and solve for P I=Prt 100 =P(0.01) (1/2) 100= P(0.05) 2,000=P multiply and solve for p I know how to get everything but the 2,000. Need the forumla on what they are multiply and how they are multiply to get the 2,000

    let see you divided both sides by 0.05 giving you 100=P*(1/100)(1/2) 100=P*(1/200) 2000=P by multiplying 200 on both sides

    =(1*1)/(100*2)=1/200

    to multiply fractions you multiply straight across on the numerator and then for the denominator like I did above

    Since we are trying to get P by itself and it is being multiplied by that 1/200 to undo this multiplication we multiply by the multiplicative inverse of 1/200 to get the multiplicative identity 1. The multiplicative inverse of 1/200 is just its reciprocal which is 200. So we multiplied by 200 to get the multiplicative identity. The multiplicative identity times any number will be that number since the multiplicative identity is 1. But since we multiply 200 on one side we have to do it to the other side of the equation

    Our formula for interest is I=Prt where r=4% and t=9 and I=42 and they ask us to solve for P. Let me see you plug those in
