A company charges a flat rate of $25 for their product but they also charge an additional $3.50
per customization. If the Smith family paid $67
for their gift, how many customizations did they
get? Write and solve an algebraic equation to
find your answer.

12 customisations.

Step-by-step explanation:

P = 3.50C + 25     where P = total payment and C = the number of customisations.

So if they paid $67:

67 = 3.50C + 25

3.50C = 67 - 25 = 42

C = 42/3.50

C = 12.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
