The expression i/pt represents the rate of instrest being charged if a loan of p dollars for t years required i dollars in intre
zysi [14]

Answer:

7.3%

Step-by-step explanation:

Given:

<em>Formula for Rate of interest </em>R:

R=\dfrac{i}{Pt}

Where i is the rate of interest.

P dollars is the loan and

t years is the time for which interest is to be paid

P =\$690\\t=3\ years\\i=\$151.11

To find:

R=?

Solution:

Putting the given values in the formula:

R=\dfrac{151.11}{690 \times 3}\\\Rightarrow R=\dfrac{151.11}{2070}\\\Rightarrow R=0.073

Multiply the above value with 100 to find the percentage.

i.e.

R=0.073\times 100 = \bold{7.3\%}

Therefore, the answer is <em>7.3%</em>

Randy, Sandy and Todd are my cousins and their combined age is 87 years. Randy is four times as old as Sandy, but Todd is actual
NISA [10]

Answer:

Randy is 48 years old

Sandy is 12 years old

Todd is 27 years old

<em></em>

Step-by-step explanation:

Given

Represent their ages with the first letters of their names:

R + S + T = 87

R = 4 * S

T = 15 + S

Required

Determine their individual ages

We'll solve the above equations using substitution method of simultaneous equations

Substitute 15 + S for T and 4 * S for R in R + S + T = 87

This gives:

4 * S + S + 15 + S = 87

4 S + S + 15 + S = 87

Collect Like Terms

4 S + S + S = 87 - 15

6S = 72

Divide through by 6

S = 72/6

S = 12

<em>This implies that Sandy is 12 years old</em>

Substitute 12 for S in R = 4 * S and  T = 15 + S

R = 4 * 12

R = 48

T = 15 + 12

T = 27

<em>This implies that Randy is 48 years old and Todd is 27</em>
