<h2>Solution 1 :</h2>

Cost of $1\frac{1}{3}$ pounds of gummy bears = $4.40

Cost of 1 pound of gummy bears :

$= 4.40 \div 1 \frac{1}{3}$

$= \frac{440}{100} \div \frac{4}{3}$

$= \frac{440}{100} \times \frac{3}{4}$

$= \frac{1320}{400}$

$= \frac{1320 \div 20}{400 \div 20}$

$= \frac{66}{20}$

$= \frac{66 \div 2}{20 \div 2}$

$= \frac{33}{ 10 }$

$= 3 \frac{3}{10}$

$= \color{plum}\bold{\$3.3}$

Therefore, 1 pound of gummy bears = $3.3

<h2>Solution 2 : </h2>

Cost of 1 pound of gummy bears = $3.3

Money Daniel has = $1.00

Quantity of gummy bears he can afford :

$= 1 \div 3.3$

$= 1 \div 3 \frac{3}{10}$

$= 1 \div \frac{33}{10}$

$= 1 \times \frac{10}{33}$

$= \frac{10}{33}$

$= 0.30$

Therefore, Daniel will be able to buy 0.30 pounds of gummy bears from Jio.

PLEASE HELP MEWhich equation can represent the graph

sergejj [24]

Answer:

y = - x^2 + 4

which agrees with answer B

Step-by-step explanation:

Notice the graph is that of a quadratic function centered on the y-axis, with negative leading coefficient (branches of the parabola pointing down), and with vertex on the y-axis at the point (0, 4).

Therefore its equation is best represented by:

y = - x^2 + 4

which also crosses the x axis at the points x = -2 and x= 2, in agreement with the graph.
