Madison spent 5/8 of her savings on a microwave oven and a refridgerator. She used 4/7 of the amount she spent to buy the refrigderator. The refridgerator cost $280 more than the microwave oven. How much savings did Madison start with ?
20/56 of her savings was spent on the fridge. 15/56 of her savings was spent on the microwave. Let the savings be S.
(20/56 - 15/56) S = 5/56 S = 280
Solve for S.
S = $3136
May you explain how did you get the 20/56 and the 15/56 . I do not know what you did there . Answer back please .
