It subtracts one more each time.
Answer:
2
Step-by-step explanation:
.78 is the answer since the 7 is in the 10ths place, and the 8 is in the hundreths place, so you stop rounding at the 8! Also, since the 1 is not greater than 5, then you don't need to round up.
Answer:
<u>Christine needs to drive 250 miles for the two plans to cost the same</u>
Step-by-step explanation:
For answering the question correctly and helping Christine, we will use the following equation:
x = number of miles driven
Cost of the first plan = 0.60x
Cost of the second plan = 50 + 0.40x
How many miles would Christine need to drive for the two plans to cost the same?
Cost of the first plan = Cost of the second plan
0.60x = 50 + 0.40x
0.60x - 0.40x = 50 (Subtracting 0.40x at both sides)
0.20x = 50
x = 50/0.2
x = 250 miles driven
<u>Christine needs to drive 250 miles for the two plans to cost the same.</u>
