Question

identify proportional relationships 1

1. bread is on sale for $0.99 a loaf. use the table to answer the question below.

number of loaves of bread | price in dollars
1 | 0.99
2 | 1.98
5 | 4.95
is there a proportional relationship between the number of loaves and the price? explain how you know.

1. to visit a state forest, you must pay a fee for your vehicle to enter plus another fee based on how many people are in your vehicle. the table shows some examples.

number of people | total price to enter forest
3 | 8
5 | 10
7 | 12
is there a proportional relationship between the number of people visiting the state park and the total price they pay to enter? explain how you know.

1. every triangle has 3 sides. is there a proportional relationship between the number of triangles ive drawn and the number of triangle sides ive drawn?

Explanation:

Step1: Check ratio for bread problem

Calculate price/loaves: $0.99/1=0.99$, $1.98/2=0.99$, $4.95/5=0.99$ (constant ratio).

Step2: Check ratio for forest problem

Calculate price/people: $8/3≈2.67$, $10/5=2$, $12/7≈1.71$ (not constant).

Step3: Check ratio for triangle problem

Sides/triangles = 3/1=3, 6/2=3 (constant ratio, 3 sides per triangle).

Answer:

1. Yes, the ratio of price to number of loaves is always 0.99.
2. No, the ratio of total price to number of people is not constant.
3. Yes, the number of sides is 3 times the number of triangles (constant ratio 3).
