Answer:
Step-by-step explanation:
<u><em>c = 0.5t + 2</em></u>
12 = 0.5t + 2 ⇒ 0.5t = 10 ⇒<em> t = 20</em>
c = 0.5(30) + 2 ⇒ <em>c = 17</em>
20 = 0.5t + 2 ⇒ 0.5t = 18 ⇒ <em>t = 36</em>
i think 20 is above 12 and 17 under 30 and 36 is on top of 20 the rule is .50(x) +2
y= 9
4 hours
25 * 8 = 200
so, 30 * 8 = 240(minutes)
240 / 60 = 4 hours
Hope it helps!
