1. nolan purchased a shirt at store a. he paid $17.50 for the shirt. scott purchased the same shirt at store b for $20.95. how much money did nolan save by purchasing the shirt at store a instead of at store b? show your work and don't forget the ! sandy is making hair bows to sell at a craft show. each hair bow requires 2/3 yard of ribbon. sandy has 30 yards of ribbon and she wants to find the number of bows that she can make. she does the following problem incorrectly. explain her error and redo the problem showing the correct answer. show your wrok step by step and don't forget the 30 ∙2/3 = 30/1 ∙ 2/3 = 60/3 = 20 bows last week, ethan bought 9 1/2 gallons of gas at $2.50 per gallon. this week, he bought 7 3/10 gallons of gas at $2.60 per gallon. what was his total cost? show you work step by step and don't forget the ( calculator is allowed but write down the numbers that you enter into your calculator). need answers asap pl and you :

1. Nolan saved $3.45

2. She can make 45 bows

3.  The total cost for gas was $42.73

Step-by-step explanation:

1.  $20.95 - 17.50 = $3.45

Nolan saved $3.45

2. You need to divide not multiply

30 ÷ 2/3

copy dot flip

30 * 3/2

90/2

45

She can make 45 bows

3.   9 /12 = 9.5 as a decimal  7 3/10 = 7.3 as a decimal

 9.5 * 2.50 = $23.75 for gas last week

 7.3 * 2.60 = $18.98  for gas this week

add   23.75 + 18.98 = $42.73

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

answer: your correct answer is b. d.
