a=3/4 square feet

Suppose Serena invests the $2,500 for 3 years and earns $255.What was the rate of interest?

Answers

I=PRT
P for Principle Amount
R for Rate
T for Time in years

255 = 2500 × r × 3
255 = 7500 × r
Divide by 7500 on both sides to isolate r
$(255)/(7500)$ = $(7500 * r)/(7500)$
7500 and 7500 cancels out

0.034 = r
0.034 × 100 = 3.4% (to convert it as a percentage)
Rate of Interest: 3.4%

Answer:

3.4%

Step-by-step explanation:

Here, Principal= $2500

Simple Interest= $255

Time= 3 years

we have to find the rate of interest

Rate of interest= $(simple interest. 100)/( p. t)$

Rate= $(255)/(2500)$ × $(100)/(3)$

Rate of interest= 34%

Hence, rate of interest is 3.4%

Hence, the correct answer is 3.4 %

At Marvin's Motorcycle's a pair of gloves sell for $85. Marvin purchases them from the manufacturer for $50. What is the percent markup on the gloves?

Answers

Answer:

60% more.

Step-by-step explanation:

So you know 50 divided by 2 is 25, so add that to 50 to get 75. then you need to add ten more so you divide 50 by 5. so then 25+5 is 30 and 30 is 60% of 50 so it is marked up by 60% more.

Answer:

Maybe 58.82%

Step-by-step explanation:

50*100= 5000, 5000/85= 58.82
