we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

t=5\ years\\ P=\$8,500\\ A=\$10,093.75\\r=?

substitute in the formula above

10,093.75=8,500*(1+r*5)

solve for r

5*r=(10,093.75/8,500)-1

r=0.0375

r=3.75\%

therefore

<u>the answer is</u>

the rate of interest is 3.75\%

Graham paid $87.45 for a pair of jeans. This amount included a tax of 40%. What was the cost of the jeans before tax?
kiruha [24]

The final price is the cost plus the tax.

Since we know the tax and a percent, we can write this as

T = C(1+r)

T = what Graham paid = $87.45

C = cost before tax

r = tax rate expressed as a decimal = .40

Plugging in what we know

87.45 = C (1+.4)

87.45 = C(1.4)

Divide both sides by 1.4

C = $62.46

2/9 of the members are boys in a community service club. if there are 95 more girls than boys, how many girls are there in club?
KengaRu [80]

Answer:

133 girls

Step-by-step explanation:

Total members = x

Number of boys = \frac{2}{9}x

Number of girls = \frac{2}{9}x +95

Number of boys + Number of girls = total members

\frac{2}{9}x+\frac{2}{9}x+95=x\\\\\frac{2}{9}x+\frac{2}{9}x=x -95\\\\\frac{2}{9}x+\frac{2}{9}x-x=-95\\\\\frac{4}{9}x-x = -95\\\\\frac{4}{9}x-\frac{9}{9}x = -95\\\\\frac{-5}{9}x=-95\\\\x = -95*\frac{9}{-5}\\\\x=19*9

x = 171

Number of boys = \frac{2}{9}*171 = 2 * 19 = 38

Number of girls = 38 + 95   = 133
