y = 2x+10
Step-by-step explanation:
y is the cost (which we don't know)

Answer:
Suppose you are in a building at 28 feet above ground level and you take an
escalator down to ground level. On the escalator, your distance above ground level
changes by - 2 feet per second. Write a linear function to describe the distance d
that
you are from ground level over time t in seconds.
Step-by-step explanation:
Cost of lack increased by 30%
new cost of lack will be = 100% + 30% = 130%
We are given that new cost = £65
Thus 130% of original cost = 65
100% of original cost = 65 × 100/130 = £50
Thus original price was £50
