It's D, you have to divide 1.54$ by 2.2pounds, then you will get the price for 1 pound. And then multiply the price (0,7$) by 5,7 pounds
4. 54 + 63 + 54=171
5. 3+3+75=81
6. 20+68=89
7. 120+180=300 x 1.48=$444
To find the intercepts, the other number will be 0 (x-intercept: when y is 0, and vise-versa).
So:
x-intercept: <u><em>0</em></u><em> + 1 = 3x - 12 -> 3x = 13 -> </em><em>x = 13/3</em><em>, </em>so it will be<em> </em>(
, 0)<em>.</em>
y-intercept:<em> y + 1 = 3*</em><u><em>0</em></u><em> - 12 -> </em><em>y = -13</em>, so it will be (0, -13).
