Fifteen years from now Ravi's age will be four times his present age.What is Ravi's present age ? Frame the equation and solve.
Archy [21]

Answer:

Ravi's age after 15 years = x+15

Ravi's age = 4 times his present age = 4x

According to question -

15 + x = 4x

=> 15 = 4x-x = 3x

=> 15 = 3x

=> x = 15/3

=> x = 5

Thus , Ravi's present age is 5 years.

Determine the simple interest when:
ivann1987 [24]

Answer:

$75.65

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year,

then, solving our equation

I = 890 × 0.0425 × 2 = 75.65

I = $ 75.65

The simple interest accumulated

on a principal of $ 890.00

at a rate of 4.25% per year

for 2 years is $ 75.65.

The selling price of a refrigerator, is $739.20. If the mark up is 20% of the dealers cost , what is the dealers cost of the ref
Lisa [10]

Mark up percentages are used to increase the prices of items

The dealers cost of the refrigerator is $591.36

<h3>How to determine the dealer cost</h3>

Represent the dealer cost of the refrigerator with x.

Given that the markup is 20% and the selling price of the refrigerator is $739.20, then we have the following equation

x = 739.20 * (1 - 20%)

Evaluate the product

x = 591.36

Hence, the dealers cost of the refrigerator is $591.36
