Answer: First option is correct.

Step-by-step explanation:

Since we have given that

Amount he owed to his bank = $200

So, Now , Bank balance would be = (-) $200

Again,

Amount he paid back = $30

So, it will denoted with (+) sign as it is deposited into the bank.

So, Bank balance would be

-200+30\\\\=(-)\$170

Hence, First option is correct.

Darina [25.2K]

If 1 ml of volume contains 1 mg of epinephrine, then 0.1 ml of volume contains 0.1 mg of epinephrine.

Let x be the number of ml you need.

Ratio: 1 ml is to 1 mg as x ml is to 0.1 mg

(1 ml)/(1 mg) = (x ml)/(0.1 mg)

Cross multiply.

1 * x = 1 * 0.1

x = 0.1

Answer: 0.1 ml

Kayla has $45 and wants to buy three shirts that are originally priced at $18 each. They are on sale for 20% off. After applying
tester [92]

Answer: No, as the total cost of the 3 shirts w/ sales tax is $45.36 and she only has $45.

Step-by-step explanation:

Start by finding the price of one shirt on sale.

18*0.2

This equals 3.6 which is how much will be deducted from the original price.

One shirt costs 18-3.6\\ when its 20% off.

This is equal to $14.40.

Since she wants to buy 3 of them we just multiply the $14.40 by 3.

14.4*3=\\

This equals $43.2 but this is without a 5% sales tax which is normally added to the total end price.

To add a sales tax you take the sales tax percent plus 1 and multiply it to the $43.2.

43.2*1.05=\\

This means the total price of Kayla's purchase will be $45.36.

This is over her $45 she has so she can not buy it.
