A sporting goods store sells right-handed and left-handed baseball gloves. In one month, 12 gloves were sold for a total revenue

stepladder [879]

Answer:

$9$ right-handed gloves and $3$ left-handed gloves were sold.

Step-by-step explanation:

Given: In one month, $12$ gloves were sold for a total revenue of $\$561$ .

right-handed gloves cost $\$45$ and left-handed gloves cost $\$52$ .

To find: How much of each type of gloves did they sell?

Solution: Let they sell $x$ right-handed gloves, and $y$ left-handed gloves.

Now, cost of each right-handed gloves $=\$45$

cost of each left-handed gloves $=\$52$

Total revenue $=\$561$

So, we get

$45x+52y=561\:\:\:...(i)$

Also, in a month $12$ gloves were sold.

So, we get

$x+y=12\:\:\:...(ii)$

Now, from $(ii)$ we get, $x=12-y$ .

Putting $x=12-y$ in equation $(i)$ , we get

$45(12-y)+52y=561$

$\implies 540-45y+52y=561$

$\implies7y=561-540$

$\implies7y=21$

$\implies y=\frac{21}{7}$

$\implies y=3$

Now, putting $y=3$ in equation $(ii)$ , we get

$x+3=12$

$\implies x=12-3$

$\implies x=9$

Hence, $9$ right-handed gloves and $3$ left-handed gloves were sold.

A botanist was measuring how tall her plant grew. After two weeks it had grown 12.93 inches.The second week alone it had grown 3

Korolek [52]

Answer:

9.5 inches

Step-by-step explanation:

The relationship is presumed to be ...

(first week's growth) + (second week's growth) = (growth in two weeks)

(first week's growth) + 3.43 inches = 12.93 inches . . . . . fill in the numbers

Subtract 3.43 from both sides of the equation:

first week's growth = 12.93 inches - 3.43 inches

first week's growth = 9.50 inches

The plant grew 9.50 inches in the first week.

If you invest 3,500 in a savings account that pays 4% simple interest how much will the new balance be after including interest?

garik1379 [7]

Answer:

New balance = 3640

Step-by-step explanation:

Given the following data;

Interest rate = 4% = 4/100 = 0.04

Principal = 3500

To find the new balance;

First of all, we would find the amount at the interest rate;

New amount = interest rate * principal

New amount = 0.04 * 3500

New amount = 140

Now, to find the new balance;

New balance = principal + new amount

New balance = 3500 + 140

New balance = 3640

How to find subtotal and sales tax? Give an example.

gizmo_the_mogwai [7]

Answer:

See explanation below.

Step-by-step explanation:

First, obtain the percentage of sales tax for a sale. Say it is 5%.

Then, obtain the sale prices, for two items say they are: $25.00 and $15.00.

Add the amounts together to obtain the subtotal:

$25.00 + $15.00 = $40.00, is the subtotal.

Multiply the amount by the percentage:

$40.00 * 5% =

40 * .05 = $2.00, is the sales tax

Add the tax to the subtotal to obtain the total amount to pay:

$40.00 + $2.00 = $42.00, is the total amount to pay.

Hope this helps!! Have an Awesome Day!! :-)
