So is an album is $18 and a picture frame is $3 less that would make picture frames $15. Now if the ratio of picture frames to albums was 4:3 and she paid a total of $1026 for all, the equation would look like this:
15f + 18a = 1026
Now add in the ratio
(15 + 15 + 15 + 15 + 18 + 18 + 18)x = 1026
114x = 1026
x = 9
Now this means the ratio fit 9 times into the end number
60 coins 30%=pennies 100-30=70% =not pennies percent menas parts out of 100 so 70%=70/100=7/20=0.7 so we want to find 70% of 60 'of' can be translated to as multiply 0.7 times 60=42 42 coins=not pennies
