Answer:
when expenses are greater than $433.33
Step-by-step explanation:
set up equations for each plan
let 'x' = prescription costs
Plan 1: y = 150 + .5x
Plan 2: y = 280 + .2x
150 + .5x = 280 + .2x
.5x = 130 + .2x
.3x = 130
x = 433.33
i checked my answer by graphing each equation and $433.33 is the break-even point where each plan would have the same costs but, after that, the expenses for Plan B are less
First you divide the total with the amount of hours you worked
45/5 = 9
9 is the amount of money you earn per hour
so your answer is $9 per hour
hope this helps
Answer:
a). 240 miles (Approx)
b). Trip can't be covered in 3 hours with a constant speed = 70 miles pr hour
Step-by-step explanation:
a). As the scale has been given at the bottom. Length of the scale represents the distance between two points.
Now by measuring the distance between these stations, approximate distance between Amarillo and Oklahoma = 4(length of the scale)
= 4×60
= 240 miles.
b). Driving at a constant speed = 70 miles per hour
Distance covered in 3 hours = 70 × 3
= 210 miles
Therefore, distance of 240 miles between these stations can't be covered with the driving speed 70 miles per hour in 3 hours.
