An unknown number w is 30 more than an unknown number p. The number w is also p less than 5

1 answer:

7 0

The problem statement gives rise to two equations.
w = 30 + p . . . . . w is 30 more than p
w = 5 - p . . . . . .. w is p less than 5

Add these two equations to get
2w = 35
w = 35/2 = 17.5
p = 5 - w = -12.5

The unknown number w is 17.5.
The unknown number p is -12.5.

RideAnS [48]

Answer: 6%

Step-by-step explanation:

Principal= $1875

Time= 10 years

Interest= $1125

Rate = Unknown

Recall that,

Interest= (Principal×Rate×Time)/100

I = PRT/100

100I = PRT

R= (100×I)/PT

Rate = (100 × 1125)/(1875 × 10)

Rate = 112500/18750

Rate= 6%

The rate is 6%
