Question

so im not that good with word problems so... here it goes.

Nadine has 7 more nickles than Delano has dimes. If Delano gives Nadine 4 of his dimes, then Delano will have the same amountof money as Nadine. How much money do they have together, assuming Nadine only has nickles and Delano only has dimes?

Answers

Damon
dimes = d
nickles = (d+7)
then later
(d-4)(.1) = (d+7)(.05)+4(.1)
Bridget
would that be the same as
.05(d+7)=(d-4).1 ?
Damon
no, you need to credit Nadine with 4 dimes (4)(.1)
Bridget
oooh!!! ok, thank you!!! so then i would get
.1d - .4 = .05d + .35 + .4
.1d - .4 = .05d + .75
.05d - .4 = .75
.05d = 1.15
d = 23
right???
Damon
