Answer:
Step-by-step explanation:
y = 0.80x + 2.50
a 7 mile ride......x = 7
y = 0.80(7) + 2.50
y = 5.60 + 2.50
y = 8.10 <=== the 7 mile ride cost $ 8.10
the ride cost 13.70.....y = 13.70
13.70 = 0.80x + 2.50
13.70 - 2.50 = 0.80x
11.2 = 0.80x
11.2 / 0.80 = x
14 = x <=== u travel 14 miles
$92.00 X 5% = $4.60
$92.00 + $4.60 = $96.60

<span>B. What was the total price of the ski jacket including tax? $96.60</span>
Answer:
Step-by-step explanation:
Your equation comes out to x + 3 = x/3. Multiplying all three terms by 3 results in 3x + 9 = x, which simplifies to 2x = -9, so that x = -9/2.
