Leokris [45]
3x-18 is less than -90
First, you add 18 to both sides of the inequality (getting 3x is less than -72).  Then you divide by 3 on both sides giving you your answer x is less than -24

suppose aaron earned 15.75 in interest for account A and 28.00 in interest for account B after 21 months if the simple interest
Kobotan [32]

Answer:

Principle for account B is greater.

<em></em>

Step-by-step explanation:

First of all, let us have a look at the formula for Simple Interest:

SI =\dfrac{PRT}{100}

Where P is the principle amount

R is the Rate of interest per annum

T is the time in years.

Time = 21 months = \frac{21}{12}\ yrs

R_1 = 3\% \\R_2=4\%

Let the Principles be P_1, P_2.

Using the formula for Simple Interest, we get:

SI_1=\dfrac{P_1\times 3\times 21}{100\times 12}\\\Rightarrow 15.75=\dfrac{P_1\times 3\times 21}{100\times 12}\\\Rightarrow P_1 = 300

SI_2=\dfrac{P_2\times 4\times 21}{100\times 12}\\\Rightarrow 28=\dfrac{P_2\times 3\times 21}{100\times 12}\\\Rightarrow P_2 = 533.33

Therefore, <em>principle for account B is greater</em>.
