The slope is -1/2. When it’s in the equation like that, the slope is always the number that has the letter X next to it.
Answer:
The Current Insurance cost = $685.43
Step-by-step explanation:
Given that Dan pays £714.73 a year on his car insurance.
Reduced Percentage = 4.1%
so
Reduced Amount = 4.1% × 714.73
= [4.1 / 100] × [714.73]
= 0.041 × 714.73
= $29.30
The current cost can be calculated by subtracting the reduced amount of 29.30 from 714.73.
so
Current Insurance cost = 714.73 - 29.30
= $685.43
Therefore, the Current Insurance cost = $685.43
C + a = 140......a = 140 - c
5.3c + 9.4a = 1086.4
5.3c + 9.4(140 - c) = 1086.4
5.3c + 1316 - 9.4c = 1086.4
5.3c - 9.4c = 1086.4 - 1316
-4.1c = - 229.6
c = -229.6 / -4.1
c = 56......so their were 56 child tickets sold
