Danika sold a painting for $435. She then auctioned off her doll collection, earning $20 for each doll. If she made at least $955 for the painting and the dolls, what is the minimum number of dolls she sold?

Equation: _________

Define Variable: _________

Solve Equation: _________

Final Answer: _________

Answer 1

Explanation:

Okay This is what is happening...

$955 total - $435 painting= $520 doll profit

First, subtract the painting Danika sold from the total. This will give you the amount she earned from the doll collection. Then, divide by the dollar amount to give the amount of dolls sold.

$520 doll profit divided by $20 = $26 fir each doll

or

Equation: 955=435-20d

Variable: d= number of dolls sold

Solve Equation: 955=435-20d

-435=-435

955-435=435-435-20d

520=20d

/20=/20 (I used "/" as my divide sign you can use the other one)

520/20=20/20

26=d

Final Answer: 26=dolls sold
