igor_vitrenko [27]

The error Giovanna made in her calculation is multiplying 7 by 2 and adding with 5/8(step 3)

<h3>Fraction</h3>

Her calculation:

7 (2 and StartFraction 5 over 8 EndFraction): 7(2 5/8)

7 (2 + StartFraction 5 over 8 EndFraction): 7(2 + 5/8)

14 + StartFraction 5 over 8 EndFraction: 14 + 5/8

14 and StartFraction 5 over 8 EndFraction: 14 5/8

Her error was multiplying 7 by 2 and adding with 5/8(step 3)

Correct calculation:

7(2 + 5/8)

= 14 + 35/8

= (112+35) /8

= 147/8

= 18 3/8

kevin borrowed $32,500 to purchase a new car. If the rate on the loan is 6% compounded annually, how much will he pay in total o

VLD [36.1K]

Answer: He would pay $43492.33 in total over the course of the 5 years.

Step-by-step explanation:

Since we have given that

Amount he borrowed = $32500

Rate of compounded annually = 6%

Number of years = 5 yr

As we know the formula for "Compound Interest':

$A=P(1+\frac{r}{100})^n\\\\A=32500(1+\frac{6}{100})^5\\\\A=32500(\frac{100+6}{100})^5\\\\A=32500(1.06)^5\\\\A=\$43492.33$

Hence, He would pay $43492.33 in total over the course of the 5 years.

Answer:

$1\frac{7}{20}$

Given data

On Monday, Jesse drank 3/4 of liter of water before jogging

and drank 3/5 of liter after jogging

In all, Jesse drank 3/4 and 3/5 liters of water
