H = hour
A = 60 + (25h) = ?
B = 120 + (20h) = ?
60 hours because 28 hours for company A x 25 dollars = 700 + starting fee is 60
28 x 25 = 700 + 60 = 760
32 hours for company B x 20 dollars = 640 + starting fee is 120
32 x 20 = 640 + 120 = 760
32 hours + 28 hours = 60 hours all together. It takes 60 hours cost the same
A= 25 x 7 + 60 = 235
25 x 7 = 175 + 60 = 235
B = 20 x 7 + 120 = 260
20 x 7 = 140 + 120 = 260
235 < 260
The cheaper one is A with 235
Answer:
4
Step-by-step explanation:
with the information given, we can express the equation:
where is the unknown number?
to clear for first we multiply the equation by 2, to eliminate the fraction:
moving all terms with to the left:
and adding +16 to each side:
and finally, dividing by 3
the number is 4.
3 x 15 = 45
3 x 14 = 42
--------------
There are 14 packages.
----------------
x = 42/3
-----> 3x=42
The answer is C because there is an open circle(not including the number it's on) on the 60 mark and the arrow goes to the left, or to the lower numbers.
