<span>First, we must calculate the amount that will be available after two years. This is given by:
Amount = initial amount * (1 + interest rate)^time
Amount = 1500 * (1 + 0.05)^2
Amount = $1,653.75
Therefore, the only items you can buy using this amount are the electronics worth $1,650</span>
Answer: The cost for one hamburger is $2.5
Step-by-step explanation:
Let x represent the cost of one hamburger.
Let y represent the cost of one fry.
The tennis coach took his team out for lunch and bought eight hamburgers and five fries for $24. This means that
8x + 5y = 24- - - - - - - - - - - -1
The players were still hungry so the coach bought six more hamburgers and two more fries for 16.60. It means that
6x + 2y = 16.6- - - - - - - - - - 2
Multiplying equation 1 by 6 and equation 2 by 8, it becomes
48x + 30y = 144
48x + 16y = 132.8
Subtracting, it becomes
14y = 11.2
y = 11.2/14
y = 0.8
Substituting y = 0.8 into equation 1, it becomes
8x + 5 × 0.8 = 24
8x + 4 = 24
8x = 24 - 4 = 20
x = 20/8
x = 2.5
The interior angles of a triangle must add to 180 degrees.
110+5x+2x=180
110+7x=180
7x=70
x=10
Then plug in the x value into each angle expression
5(10)=50 degrees
2(10)=20 degrees
Answer:
a) The cost of ribeye steak dinners is $ 16.96.
b) The cost of grilled salmon dinners is $ 23.37.
Explanation:
Let the cost for ribeye steak dinners be m and cost for grilled salmon dinners be n.
A waitress sold 10 ribeye steak dinners and 18 grilled salmon dinners, totaling $590.39 on a particular day.
So, we have
10 m + 18 n = 590.39 -------equation 1
Another day she sold 22 ribeye steak dinners and 9 grilled salmon dinners, totaling $583.49
So, we have
22 m + 9 n = 583.49 -------equation 2
equation 2 x 2
44 m + 18 n = 1166.98 -------equation 3
equation 3 - equation 1
44 m + 18 n - ( 10 m + 18 n ) = 1166.98 - 590.39
m = 16.96 $
Substituting in equation 1
22 x 16.96 + 9 n = 583.49
n = 23.37 $
a) The cost of ribeye steak dinners is $ 16.96.
b) The cost of grilled salmon dinners is $ 23.37.
