((10.48÷9.99)−1)×100

Answer:

Percent increase is 4.90%.

Step-by-step explanation:

John paid $9.99 monthly per thousand on his original loan, so number of thousands are = [tex]\frac{60000}{1000}[/tex]= 60

Monthly payment at $9.99 was:

[tex]9.99\times60=599.4[/tex] dollars

Now, new monthly payment  at 10.48 is :

[tex]10.48\times60=628.80[/tex] dollars

Percent increase is given as:

[tex][\frac{10.48}{9.99}-1]\times100[/tex]

= [tex]\frac{10.48-9.99}{9.99}\times100[/tex]

= 4.90%
