Answer: she is thinking the line might go through the dots on the graph
Step-by-step explanation:
Because when you put the line through the dots on the graph it looks more efishiant. Sorry bad spelling.
Let the number of quarter be x and that of nickels be y
total number of coins will be:
x+y=85
thus
x=85-y.........i
total amount of money will be:
0.25x+0.05y=14.25....ii
substituting i in ii we get:
0.25(85-y)+0.05y=14.25
21.25-0.25y+0.05y=14.25
7=0.2y
y=7/0.02
y=35
thus
x=85-35=50
the number of quarters was 50 and that of nickels was 35
Answer:
In mathematics, a percentage is a number or ratio that represents a fraction of 100
J not here because
Brand C does not have a lower unit cost than brand B
Brands D does not have a higher cost than brand A
And brand A and C don’t have the same cost
First, we know that it is 2017 so:
2017-2001=16 years
Put that into the equation:
C= 2,000(1.1)16
Find out the answer...
What you should have got was 35,200 and that, is the total off the tuition since 2001. Since we need to know what the tuition cost was in 2001 we:
Divide: 35,200/16 =2,200
Answer is: The tuition cost in 2001 was $2,200.
