Danny's Bike Shop sells a certain model of racing bike for $550. The same bike can be bought at a competing shop for 7 percent l
AleksAgata [21]

Answer:

$511.5

Step-by-step explanation:

Given: Selling price of bike at Danny´s shop is $550

           Bike is sold 7% less at competitor´s shop.

Lets find the discounted amount at Danny´s competitor shop.

∴ \frac{7}{100} \times 550 = \$ 38.5

Now, finding the cost of bike at Danny´s competitor.

Cost of bike at Danny´competitor= (\textrm{Price at dannys shop - discount provided by competitor})

Cost of bike at Danny´s competitor= 550-38.5= \$511.5

∴ Cost of bike at Danny´s competitor is $511.5.

Tina had $47.10 in her bank account on Monday. She withdrew $25 on Monday and also made a deposit of an amount d that she cannot
nalin [4]
The correct answer is a.  47.10 - 25 + d = 97.43.

This is because you have to subtract the $25, because it is a withdrawal, or taking out of money.
This rules out options C and D.  

Also, Tina made a deposit of an amount that she can't remember.  A deposit is adding a certain amount of money, so you have to +d.  

This rules out option B.

The only option left is option A, which makes complete sense.
