A recording studio charges musicians an initial fee of $100 to record an album. Studio time cost an additional $1 per minute. Write and graph an equation that models the total cost of recording an album over one afternoon.

$340

Step-by-step explanation:

Given data

Inititial fee= $100

cost per minute= $1

Let the total charge for x minutes by y

Hence the expression for the total charges after x minutes is

y= 100+1x

y=100+x

But an after is from 12pm - 4pm= 4 hours

x=4*60

x=240minutes

y=100+240

y=$340

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
