Question

145 pennies + 42 dimes + 12 quarters

Answer 1

so I did 42 x 10, cause 1 dime equals 10 cents and 12 x 25, cause 1 quarter is 25 cents.

42 x 10 = 420 ($4.20)

12 x 25 = 300 ($3.00)

145 pennies = $1.45

Your answer:

$8.65

Answer 2

Answer: i belive your awnser is $8.65

* i might be wrong*

Explanation:

since dimes = 10 sents we will have to multiply. so therefore it would be 42*10= 420 in decimal form it would be 4.20 so all we got to do now is add 3 dollars since 12 quarters = 3 dollars so therefore the equation would be 1.45+4.20+ 3 therefore leading it to be $8.65 so i hope this helps
