Answer:

<h2>$36.00</h2>

Step-by-step explanation:

$12.00 - the total cost of 4 of equally priced gloves

$12.00 : 4 = $3.00 - the cost of 1 glove

The cost per glove is increased by $1.00. Therefore new cost of 1 glove is

$3.00 + $1.00 = $4.00

The total cost of 9 of gloves at the new price:

9 × $4.00 = $36.00

You want to save $10,000 to buy a new car You doposit 6500in an account earning 7.5% simple interest. After how long will you ha
Stells [14]

Answer:

After 7.5 years we will have enough money in the account to purchase the car.      

Step-by-step explanation:

Amount needed to be saved = $10000

Principal = $6500

So, Simple Interest = $3500

Rate of Interest = 7.5%

                         = 0.075

Now, Simple Interest = Principal × Rate × Time

⇒ 3500 = 6500 × 0.075 × Time

⇒ 3500 = 487.5 × Time

⇒ Time = 7.18 years ≈ 7.5 years

Hence, after 7.5 years we will have enough money in the account to purchase the car.
