Answer:
3x+18
Step-by-step explanation:
Step-by-step explanation:
1. a) q=4+0.8(7)
q=4+5.6
q=9.6
b) q=4+0.8(100)
q=4+80
q= 84
2. a) 12=4+0.8p
-4 -4
<u>8</u>=<u>0.8p</u>
0.8 0.8
10=p
b) 60=4+0.8p
-4 -4
<u>56</u>=<u>0.8p</u>
0.8 0.8
70=p
49.99 = 0.6x, where x = original coat of jacket.
To solve for x divide both sides by 0.6, and you get x = $83.32 (rounded)
