Question

Can somebody please help me tbh i dont understand this :'v

Answer 1

Answer:

1. $2.50

2. 120 bagels

Step-by-step explanation:

1. First, we are told that for every twelve bagels, it costs $5

we can use this information to set up the ratio:

$\frac{5}{12}$

Now, for the first question, we have to figure out how much it would cost to buy six bagels. We can use x for the cost since it is unknown as write the ratio:

$\frac{x}{6}$

since the rate of change is constant, we can set these two ratios equal to each other and cross multiply to solve for x.

$\frac{5}{12}$ = $\frac{x}{6}$

5 * 6 = 12 * x

30 = 12x

x = 2.5

it would cost $2.50 for 6 bagels.

2. For this problem, we can use the same first ratio of:

$\frac{5}{12}$

Now in this problem, the amount of bagels is unknown. we can use y to represent the number of bagels and set up the ratio of

$\frac{50}{y}$

we can make these two ratios equal to each other and cross multiply

$\frac{5}{12}$ = $\frac{50}{y}$

5 * y = 12 * 50

5y = 600

y = 120

For $50, you can buy 120 bagels

hope this helped!
