This can be
solved by solving the slope of the line. First let y be the rating of the test
and x be the number of incorrect answers. Slope can be solved using the formula:
M = ( y2 –
y1 ) / ( x2 – x1)
M = ( 90 –
98) / ( 5 -1 )
M = -2
<span>So the model
has a negative slope</span>
15 x .42= $ 6.30 Flour
8 x 3.99 = $31.92 Utter
1 x .67 = .67 Salt
30 x 1.49 = $ 44.70 Apples
Total = $83.59
Dollar amount is $83
Change amount is .59
If Jamal had $84.00 to spend his change was .41
