Answer:
The original price of the tent was $130,00.
Step-by-step explanation:
The original price of the tent will be called "x". The store increased the value by 25%, so the new value is the original one plus 0.25 of the original one, so the new value is 1.25*x. The costummer paid the increased value less the $10 from the coupon, so we have:
paid = 1.25*x - 10
Since he paid $152.5 for the tent we can compute the original value as shown bellow:
152.5 = 1.25*x - 10
1.25*x = 152.5 + 10
1.25*x = 162.5
x = 162.5/1.25 = 130
The original price of the tent was $130,00.
I'd say 7.360 / 78.000 * 100 = 9,4359 %
Answer:
a. (0,5) and (4,0)
b. -5/4
c. y = -5/4x + 5
Step-by-step explanation:
The intercepts are where the line crosses the axis. It crosses at (0,5) and (4,0).
The slope of the line is how much it rises over how much it runs. It rises -5/4 from each intercept to the other.
The linear equation should be written as y = mx+b where b = 5 and the slope -5/4.
So the equation is y = -5/4x + 5.
The number of members in a baseball club is shown with the function:
f ( x ) = 25 * 1.45^x
When: x = 0: f ( 0 ) = 25
When x = 1 f ( x ) = 25 * 1.45 ≈ 36
When x = 3, f ( x ) = 25 * 1.45³ ≈ 76
Answer:
Graph D best represents this function.
