Answer:

8 pens

Step-by-step explanation:

<h2><u>Finding the number of pens bought </u></h2>

pencil costs 0.27

pen costs 0.32

6 * pencils + x pens = 4.18

6 * 0.27 + x * 0.32 = 4.18

1.62 + 0.32x = 4.18

0.32x = 4.18 - 1.62

0.32x = 2.56

x = 2.56/0.32

x = 8

<u>hence 8 pens were bought </u>

Trevor’s total employment compensation is $33,500. If Trevor has no job expenses and his gross pay is $28,600, then his total em
EleoNora [17]

we know that

Total\  employment\  compensation=gross\  pay+employee\  benefits-job\  expenses

in this problem

Total\  employment\  compensation=33,500\ dollars

gross\  pay=28,600\ dollars

job\  expenses=0

Step 1

Find the total employee benefits

Let

EC------> total employment compensation

EB--------> total employee benefits

GP------> gross pay

JE------> job expenses

EC=GP+EB-JE

33,500=28,600+EB-0\\ EB=33,500-28,600\\ EB=4,900\ dollars

Step 2

Find the percentage of the total employee benefits

we know that

total employee benefits is equal to 4,900\ dollars

gross pay is equal to 28,600\ dollars

by proportion

\frac{28,600}{4,900} =\frac{100}{x} \\ \\ x*28,600=100*4,900\\ \\ x=\frac{100*4,900}{28,600}

x=17.1%

therefore

the answer is the option

d. 17.1

Ben has 50 drinks and paid 2$ for each. What is 67% of the final price ?
Debora [2.8K]

67% of final price is $67.

Step-by-step explanation:

Given,

Number of drinks Ben has = 50

Amount paid for each drink = $2

Amount paid for 50 drinks = 50*2

Amount paid for 50 drinks = final price = $100

67% of final price = \frac{67}{100}*100

67% of final price = \frac{6700}{100}

67% of final price = $67

67% of final price is $67.
