A sewing machine is at a 20% off sale. The original price was $340. How much does the sewing machine cost at a 20% off sale?

Anvisha [2.4K]

Answer:

272$

Step-by-step explanation:

Since it is at a sale of 20% off that means that we will have to subtract 100% from 20% which is 80%

Now to find the exact value, we will have to multiply 80%, or 0.80 with 340

0.80*340= 272$

Therefore our answer is 272$

Answer:

Lawns ---Earnings

1 ----------------- 10

2 ----------------- 20

3 ----------------- 30

5 ----------------- 50

Step-by-step explanation:

Given

Earnings = $10 per lawn

Required

Complete the table

Let y be the earnings for x number of lawns

Since he earns $10 per x lawns, then the expression is:

$y = 10x$

To complete the table, we have the following:

When x = 1

$y = 10 * 1 = 10$

When x = 2

$y = 10 * 2 = 20$

When x = 3

$y = 10 * 3 = 30$

When x = 5

$y = 10 * 5 = 50$

So, the complete table is:

Lawns ---Earnings

1 ----------------- 10

2 ----------------- 20

3 ----------------- 30

5 ----------------- 50
