Verified Answer :

Answer:

Total amount donted by Danny class is 1.21d .

Option (a) is correct .

Step-by-step explanation:

As given

Ron’s class donated d dollars to a local charity.

Danny’s class donated 21% more than Ron’s class.

21% is written in the decimal form .

\(= \frac{21}{100}\)

= 0.21

Danny class donted more than Ron class = 0.21 × Ron class donated

                                                                    = 0.21d

Total amount Danny class donated = Ron class donated +  Danny class donted more than Ron class

                                                          = d + 0.21d

                                                         = 1.21d

Therefore total amount donted by Danny class is 1.21d .

Option (a) is correct .
