1.An advertising company charges $40 per half-page advertisement and $75 per full-page advertisement. Michael has a budget of $800 to purchase 13 advertisements. Write a system of equations and show me how you broke it down

H + F = 13

40H + 75F = 800

He can purchase 8 full-page advertisement and 5 half-page advertisement

Step-by-step explanation:

Let H = half-page advertisement and F= full-page advertisement.

The total amount of advertisements that Michael can buy is:

If each H costs $40 and each F costs $75, the total amount spent by Michael is:

Both equations give us the following system:

Solving the linear system:

He can purchase 8 full-page advertisement and 5 half-page advertisement

answer: 25 is the correct answer

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
