Answer:

Step-by-step explanation:

Given:

(y/y - 4) - (4/y + 4) = 32/y^2 - 16

Note y^2 - 16 = (y - 4 ) × (y + 4)

Multiplying the equation; both sides by y^2 - 16,

y (y + 4) - (4(y - 4)) = 32

y^2 + 4y - 4y + 16 = 32

y^2 = 32 - 16

Squaring both sides,

y = sqrt(16)

= 4

The poetry club had its first bake sale, and they made $79.35. The club members are planning to have 4 more bake sales. Leslie s
Nesterboy [21]

During its first bake sale, the poetry club made $79.35. If we round up to $80, this will make it easier to estimate how much they will make if they have 4 more bake sales (5 altogether). Next, we should use multiplication to determine how much money they will earn altogether after 5 bake sales. Five times $80 equals $400. Leslie accidentally multiplies by 50 because she moves the decimal one place too far.

<h3>Further Explanation</h3>

Estimation

Estimation is when you use an approximate calculation to make a prediction. It is important here to note that an estimation is different than guess. In both instances, one should use whatever knowledge is at their disposal; however, an estimation usually uses rounding and actual calculations.

Rounding

When making an estimation, rounding is an effective tool to use. Often numbers are rounded to the nearest whole number or place value. This can make it easier to do a quick calculation. In the word problem, the nearest whole number to 79.35 is 80. This makes it easier to multiply the dollar amount because there are fewer numbers to multiply.
