Answer:
A) t=0.2(60.5)
B) d=0.15(34)
C) t=0.9(157.3)
D) p=100(10.49/58.25)
E) t=0.85(94.2+0.2(94.2))
Step-by-step explanation:
A)
Let the tip be represented by t. The tip is 20% of $60.50:
t=0.2(60.5)
B)
Let the money they save be represented by d. Their discount is 15% of $34:
d=0.15(34)
C)
Let the new total be represented by t. Their discount is 10%, so they will only be paying 90% of $157.30t:
t=0.9(157.3)
D)
Let the percentage be represented by p. The tip is $10.49, to find this as a precent of the $58.25 bill, divide the tip by the bill and multiply by 100:
p=100(10.49/58.25)
E)
First find the total after the tip but before the coupon.
Their tip is 20% of $94.20, and their total before the coupon is $94.20 plus the tip: 94.2+0.2(94.2)
Now find their final total.
Let the final total be represented by t. The discount is 15%, so they will only be paying 85% of the total after tip:
t=0.85(94.2+0.2(94.2))

Step-by-step explanation:
<u>Reason</u><u> </u><u>1</u>
- When we solve the equation by combining both equations in one, the variable will become 0.
<u>Proof</u>

Combine like terms.

See that the equation is false no matter which numbers you substitute in x-term.
<u>Reason</u><u> </u><u>2</u>
- Both graphs are parallel and don't have any intercepts to each others.
<em>See the attachment below for graphs</em>.
Since both graphs do not really have intercepts, that means they do not provide any solutions. Hence, no solutions.
