Katelyn has a job and her hourly wage is $6.50 an hour. She receives 9% of the tips on any given night. If she works 7 hours and her job makes $1,342.25 in tips during that time, how much money does she earn?

She earns $166.3024

Step-by-step explanation:

Katelyn's hourly wage = $6.50

Her 7 hours wage = 7 × $6.50 = $45.5

Tip made = $1342.25

Katelyn's share of the tip made = 9/100 × $1342.25 = $120.8025

Her earnings = $45.5 + $120.8025 = $166.3025

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
