AnnZ [12381]

Answer:

13 Millilitres.

Step-by-step explanation:

Yoku applies 2ml to cover 50cm^2 of his skin.

He seeks to find out how many millilitres he needs to cover 325cm^2 of his body.

With 2ml, Yoku covers 50cm^2 of his skin

He will use \frac{2}{50}ml of sunscreen for covering 1cm^2 of his skin.

Thus:

For covering 325cm^2 of his body, he will require:

\frac{2}{50} X 325 ml\\=13ml

he would need 13 Millilitres.

Josiah works at an electronics store as a salesperson. Josiah earns a 2% commission on the total dollar amount of all phone sale
tester [12383]

Response: the equations are

0.02x + 0.07y = 156

y = 300 + x

Step-by-step explanation:

Let x denote the dollar amount from phone sales made by Josiah.

Let y indicate the dollar amount from his computer sales.

Josiah receives a 2% commission on his phone sales total and 7% on his computer sales. He accumulated a total of $156 in commission, leading to the equation

0.02x + 0.07y = 156 - - - - - - - - - - -1

Furthermore, it’s given that Josiah had $300 more in computer sales than in phone sales, expressed as

y = 300 + x
