Rachel works for a clothing store. She is paid $150 every week plus a 10% commission on any clothes that she sells.
zimovet [89]

Answer:

$165

Step-by-step explanation:

Rachel works for a clothing store. She is paid $150 every week plus a 10% commission on any clothes that she sells.

Let's find the total amount she is being paid per week

Amount paid originally = $150

Percentage Commission = 10%

Commission = 10% of 150

Commission = 0.1×150

Commission = $15

Total amount paid = originally amount + Commission

Total amount paid = $150+$15

Total amount paid =$165

Hence the amount paid to Rachel okus Commission is $165

Jake buys a fruit smoothie and a protein bar for​ $5.90. Kobe buys 2 fruit smoothies and 4 protein bars. He pays​ $16.80. What i
Andrei [34K]

Answer:

Fruit smoothie: $3.4

Protein bar: $2.5

Step-by-step explanation:

Let x represent cost of fruit smoothie and y represent cost of protein bar.

We have been given that Jake buys a fruit smoothie and a protein bar for​ $5.90. We can represent this information in an equation as:

x+y=5.90...(1)

x=5.90-y...(1)

We are also told that Kobe buys 2 fruit smoothies and 4 protein bars. He pays​ $16.80. We can represent this information in an equation as:

2x+4y=16.80...(2)

Upon substituting equation (1) in equation (2), we will get:

2(5.90-y)+4y=16.80

11.80-2y+4y=16.80

2y=16.80-11.80

2y=5

y=\frac{5}{2}=2.5

Therefore, each protein bar costs $2.5.

Upon substituting y=2.5 in equation (1), we will get:

x=5.90-2.5=3.4

Therefore, each fruit smoothie costs $3.4.
