Conrad Savings Bank has a $50 overdraft fee. On Friday, Mr. McQuire deposited his paycheck of $468.92 for a total account balanc

stira [4]

Answer:

<em>The current balance in the McQuire's account is $-605.11</em>

Step-by-step explanation:

Mr. McQuire deposited his paycheck for a total account balance of $712.34 on Friday.

The next morning, his wife wrote a check for $1,267.45

As, the total account balance is less than the amount of check, so the bank will charge a $50 overdraft fee.

That means, the total amount that will be deducted from his account $=(\$1267.45+\$50)= \$1317.45$

So, the current balance in the McQuire's account $=(\$712.34-\$1317.45)= \$-605.11$

On a factory floor, 30 out of every 140 toy robots is defective. What percent is defective?

yaroslaw [1]

Answer:

$21.43\%$

Step-by-step explanation:

we know that

To find out the percent of robots which are defective, divided the number of defective robots by the total number of robots and multiply the result by 100

Let

x ----> the number of defective robots

y ----> the total number of robots

p ---> percentage of robots which are defective

so

$p=\frac{x}{y} (100)$

we have

$x=30\\y=140$

substitute

$p=\frac{30}{140}(100)$

$p=21.43\%$
