Answer:
85% off $51 is $43.35 which equals to $7.65
Amanda paid only $7.65 for the 85% off the original price.
Step-by-step explanation:
1. combine like terms (2x and -7x) to create -5x
2. subtract 5 from each side to create: -5x=10
3. divide both sides by -5
4. x=-2
The question seems to be pointing towards a multiple choice response but I will do my best. The first equation would be 15x+12y=9.30 and the second would be 10x+4y=4.60, x represents flour and y represents sugar.
Hope this helps.
