14. Jasmine invested $4000 in a Building Society which paid simple interest at a rate of 7% per annum
to its investors. After 2 years, the rate was increased
to 7.6% per annum. Find the amount she had at
the end of 7 years.

., plz answer this question iam having a problem solving it

In 7 years she will have $6080

Step-by-step explanation:

1. She started with $4,000

2. Increased in 7% per year

(What is 7% of 4000?)

7 percent *4000 =

(7:100)*4000 =

(7*4000):100 =

28000:100 = 280

$4,000 +280 +280 > 280 is put twice because of the two years = 4560

(NOW It has increade 7.6% for the rest of the 5 years)

4560+(304)5=6080

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
