Philippa took out a $860 discounted loan for a period of m months at a simple interest rate of 6%. the amount she actually received into her bank account was $838.50. calculate the value of m.

5 Months

Step-by-step explanation:

For this calculation we use the fact that the total interest is $860 − $838.50 = $21.50. Therefore using  I = Prt,

we get  $21.50 = $860 × 0.06 × t.

Solving this for t gives t = 0.416 =512. Hence m = 5.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
