Answer:
Her uncle's age = 47 years
Step-by-step explanation:
Sophia = 12 years old
Her Uncle Reynald tells her that if she adds 5 to her age,
= 12 + 5
multiplies the sum by 3
= (12 + 5) × 3
and then subtracts 4 from the product
= {(12 + 5) × 3} - 4
she will find his age
{(12 + 5) × 3} - 4
= (17 × 3) - 4
= 51 - 4
= 47
Her uncle's age = 47 years
Sophia wrote:
12 + 5 × 3 − 4
Using PEMDAS
P - product
E - exponent
M - multiplication
D - division
A - addition
S - subtraction
Sophia's expression can be written as = 12+(5*3)-4
= (12 + 15) - 4
= 27 - 4
= 23
Sophia's expression is wrong
Answer:
1.41 %
Step-by-step explanation:
Principal amount (P) = $500
Time (T) = 2 weeks = 2 * 7 days = 14 days
Interest = $80
So,
Interest = P*T*
=> 80 = 500 * 14 *
=> 80 = 7000 *
Flip the sides of the equation
7000 * = 80
Multiply both sides by 100
7000 * * 100 = 80 * 100
Cancel out the 100's on the top and bottom from the left side
7000 * R = 8000
Divide both sides by 7000
=
Cancel out the 7000's on the top and bottom from the left side
R = 1.41 %
So, the periodic interest rate of the loan = 1.41 %
