Answer:
8x + 3y = -47
Step-by-step explanation:
1. Use the y = mx + b form to find b:
2. Plug in b for the new equation:
3. Get rid of the denominators and simplify everything into standard form
(ax + by = c)
So first we need to get rid of that naughty sales tax so we need to divide 30.45 by 1.05 since 30.45 is 105% of the pre-tax price. We get the answer of 29 and subtract 12 from 29 since the long fleece socks cost 12 bucks and we get 17 dollars. Since there are 2 pairs of regular songs we divide 17 by 2 and get 8.5
So the regular socks cost $8.50
Checking work 8.5*2=17
12+17=29
1.05*29=30.45
