Question

Shandra owns a goldfish that currently weighs 0.50 ounces. With each inch that the goldfish grows, the goldfish weighs an additional0.15 ounces.PARTACreate an equation that Shandra can use to find the number of inches, r, it will take for the goldfish to weigh 1.1 ounces.PART BHow many more inches does the goldfish need to grow to weigh 1.1 ounces?inches

Answer 1

A.

The initial weight of the goldfish is 0.5 ounces.

Then, for each inch it grows, its weight increases by 0.15 ounces.

So, using the variable r to represent the number of inches it grew, we can write the following equation to determine the value of x for a weight of 1.1 ounces:

$0.5+0.15r=1.1$

B.

Solving the equation for r, we have:

$\begin{gathered} 0.15r=1.1-0.5 \\ 0.15r=0.6 \\ r=\frac{0.6}{0.15} \\ r=4 \end{gathered}$

It needs to grow 4 more inches.
