When Kevin bought a new bike ramp, he borrowed $1,200 at a rate of 18% for 9 months. How much interest did he pay?
AURORKA [14]

We would apply the formula for determining simple interest which is expressed as

I = PRT/100

I is the interest

P is the principal or initial amount

R = interest rate

T = time in years

From the information given,

P = 1200

r = 18

Since there are 12 months in a year,

T = 9/12 = 0.75

Thus,

I = (1200 x 18 x 0.75)/100

Interest = $162

The sum of an integer and 7 more than the next consecutive integer is 66. find the integer
Cloud [144]

If the sum of an integer and 7 more than the next consecutive integer is 66 then the integers are 29 and 30.

Given that the sum of an integer and 7 more than the next consecutive integer is 66.

Integer is a number that is written without a fraction component. It can be positive as well as negative.

let the first integer be x.

Consecutive integer will be x+1.

Sum of integer and 7 more than the next consecutive integer is 66.

Sum according to the given information=x+x+1+7

=2x+8

2x+8=66

2x=66-8

2x=58

x=58/2

x=29

Next integer=29+1-30.

Hence if the sum of an integer and 7 more than the next consecutive integer is 66 then the integers are 29 and 30.
