A garden centre pays £16 for a tree one week. The next week, the garden centre pays £20 for a tree. Work out the percentage change in the price paid for a tree.

Percent change in the price paid for a tree is 25%.

Step-by-step explanation:

It is given that:

Amount of tree paid for one week = £16

Amount of tree paid in next week = £20

Change = 20 - 16 = £4

Percent increase =

Percent increase =

Percent increase = 25%

Therefore,

Percent change in the price paid for a tree is 25%.

step-by-step explanation:

i looked it up

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
