Wally counted 200 pennies from his piggy bank. He kept 80% of them. How many pennies did Wally keep?

I believe he kept 160 pennies.

Step-by-step explanation:

10% of 200 is 20 (200 divided by 10) so 20% is 40 pennies. 200 minus 40 is 160 (pennies)

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
