First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100. If the answer is a negative number, this is a percentage increase.
Answer:
<h2>$32</h2>
Step-by-step explanation:
Step one:
Given that membership is $9 and the cost per visit is $1
let the number of visits be x
and the total cost be y
the total cost for the situation is modeled as
y=mx+c-----equation of a line
Step two:
given that x=23, we can solve for the totals cost as
by substituting we have
y=1*23+9
y=23+9
y=32
<u>The total cost for 23 visits is $32</u>
Answer:
x<3
Step-by-step explanation:
Answer:
y=-9
Step-by-step explanation:
Y = number of yellow fish
G = number of green fish
Y = G - 6
Y = 0.40 * (Y+G)
G - 6 = 0.4*(G-6+G)
G - 6 = 0.4*(2G-6)
G - 6 = 0.8G -2.4
0.2G = 3.6
G = 3.6/0.2=18
There are 18 green fish.
