Answer:

friend this is not a formula

Step-by-step explanation:

ax ± b = c. All problems like the following lead eventually to an equation in that simple form.

Jane spent $42 for shoes. This was $14 less than twice what she spent for a blouse. How much was the blouse?

Solution. Every word problem has an unknown number. In this problem, it is the price of the blouse. Always let x represent the unknown number. That is, let x answer the question.

Let x, then, be how much she spent for the blouse. The problem states that "This" -- that is, $42 -- was $14 less than two times x.

Here is the equation:

2x − 14 = 42.

2x = 42 + 14

= 56.

x = 56

2

= 28.

The blouse cost $28.

If tomatoes are $3.22 per pound and Nico spends $5.76 on tomatoes, how many pounds did he purchase?
juin [17]

In order to find out the amount of pounds of tomatoes purchased:

  • We have to know how much one pound is ($3.22 per pound)

  • Total Nico spent ÷ Price per pound

    So it would be

  • 5.76 ÷ 3.22 = 1.78881987578

Rounding our decimal number:

  • If we round to our nearest tenths it would now be 1.8

Answer:

Therefore, the total number of pounds Nico purchased for $5.76 is 1.8lb.
