Solve for x. Round your answer to the nearest tenth if necessary.

Answer:

x ≈ 11.1

Step-by-step explanation:

using the cosine ratio in the right triangle

cos42° = $(adjacent)/(hypotenuse)$ = $(x)/(15)$ ( multiply both sides by 15 )

15 × cos42° = x , then

x ≈ 11.1 ( to the nearest tenth )

Sarah bought a lawnmower for $320. She signed up for the buy now pay later plan at the store with the following conditions: $100 down and payments of $25 for the next 12 months. The extra cost paid by taking this plan is equivalent to what actual yearly rate of interest? A. 67% B. 65% C. 25% D. 85%

Answers

The yearlyrate of interest is equivalent to the extra cost paid by taking the plan of $100 down and payments of $25 for the next 12 months is 25%

Option C is the correct answer.

What is simple interest?

It is the interest calculated on the principal at a given rate for a time period.

We have,

Sarah bought a lawnmower for $320.

Principal = $320

She signed up for the buy now pay later plan at the store with the following conditions:

$100 down and payments of $25 for the next 12 months.

This means,

Amount paid = $100

Amount paid for the next 12 months = $25

The totalamount paid in 12 months:

= 100 + 12 x 25

= 100 + 300

= $400

The extraamount paid:

= 400 - 320

= $80

The yearlyrate of interest:

Simple interest = Principal x Rate x Time / 100

80 = (320 x Rate x 1) / 100

8000 = 320 x Rate

Rate = 8000 / 320

Rate = 25%

Thus,

The yearlyrate of interest is equivalent to the extra cost paid by taking the plan of $100 down and payments of $25 for the next 12 months is 25%

Option C is the correct answer.

Cost of the lawnmower bought by Sarah = $320
Amount of down payment made by Sarah = $100
Amount paid by Sarah in 12 months = (12 * 25) dollars
= 300 dollars
Total amount paid by Sarah = (300 + 100) dollars
= 400 dollars
Excess amount paid as interest by Sarah = (400 - 320) dollars
= 80 dollars
Actual yearly rate of interest paid by Sarah = (80/320) * 100 percent
= 25 percent
So 25% yearly interest was paid by Sarah. The correct option is option "C".
