Lisa got a $50 gift card to an online music store. She uses the gift card to buy an album for $10. She also wants to use the gift card to buy some individual songs. Each song costs $1.50. Which of these inequalities describes the situation for the total amount that Lisa can spend, where n is the number of songs Lisa wants to buy?

Group of answer choices

10 - 1.50n ≤ 50

10 + 1.50n ≥ 50

10 - 1.50n ≥ 50

10 + 1.50n ≤ 50

Whats the topic

Step-by-step explanation:

The fourth answer choice: 10 + 1.50n < 50

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
