Help asap A coffee mixture has beans that sell for $0.52 a pound and beans that sell for $0.28. If 130 pounds of beans create a mixture worth $0.64 a pound, how much of each bean is used? Model the scenario then solve it. Then, in two or more sentences explain whether your solution is or is not reasonable.

Let the proportion of the $0.20 be x

Then the proportion of the $0.68 is 1−x

Set the target at $0.54

Dropping the unit of measurement ($ ) for now we have

0.20x+(1−x)0.68=1×0.54

0.20x−0.68x+0.68=0.54

−0.48x+0.68=0.54

Lets get rid of the decimals for now and multiply everything by 100

−48x+68=54

48x=68−54

x=1448

x=724 of the blend at $0.20

So the proportion of the $0.68 is 1−724=1724

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
