(b) What is Jenna’s total cost given she purchases 4 small floral arrangements? Show your work.

Respuesta :

Answer:

a y=(15)x+100  

b y =(15) (4) +100    y =160

Step-by-step explanation:

y = mx + b

large arrangment cost $50

$50 x 2 = 100

b=100

x = the number of small arrangments that jenna is buying .in this case 4 so

x= 4

m is the cost of one small arranment so

m=15

y represents the total cost jenna pust may in dollars so you would do

15 x 4 =60  50x2=100  100 +60 = 160

giving y = 160
