The equation y = 0.1x + 1.61 can be used to predict the price per pound of ground beef, where x is the number of years since 1996.

according to the model, what will the price per pound of ground beef be in 2017?
$3.81
$3.71
$3.61
$3.31

2017 - 1996 = 21
So x = 21

y=0.1(21)+1.61
y=2.1+1.61
y=3.71

$3.71 is your answer

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
