Answer: D (2.4, 2)
Step-by-step explanation:
The place where the lines intersect is around 2.5, 2. So cross out the first two options. For the last two, it's different in x-coordinates. The intersection point seems to be behind 2.5, so D is the correct answer. Hope this helps, please consider making me Brainliest.
So for this we will be using a system of equations, with one equation representing Shakira's sales and the other representing Jeff's sales. Our equations are such (Let x = oranges and y = grapefruit)

For this, I will be using the elimination method. So firstly, multiply both sides of the second equation by -4: 
Next, add 5x+8y=235 and -12x-8y=-340 to get -7x = -105 . From here we can solve for x.
For this, just divide both sides by -7, and your answer is going to be x = 15.
Now that we know what x is, just substitute x for 15 in either equation to solve for y. For this I will be using the second equation.

Since we know that oranges cost $15 and grapefruit cost $20, just add them together to get your answer, which is $35.
8 / 10 = 1/5 = 0.2
Mario's hourly pay rate increased by <span>$</span>0.2
1 man earns 810 / 12 = $67.5 in 10 days
by proportion 1 man will earn 0.8 * 67.5 = $54 in 8 days
So 14 men will earn 54 * 14 = $756 in 8 days.
