The cost of 3 burritos is $22.50. if the cost is proportional to the number of burritos ordered, which of the following prices is not an equivalent rate?

a. 7 burritos for $51.50

b. 2 burritos for $15.00

c. 5 burritos for $37.50

d. 4 burritos for $30.00

A. 7 burritos for $51.50

Step-by-step explanation:

22.50/3=7.50

1 burrito cost $7.50

2 burritos will cost $15.00

2×7.50=15

5 burritos will cost $37.50

5×7.50=37.50

4 burritos will cost $30.00

4×7.50=30.00

However, 7 burritos will not cost $51.50 because 7×7.50=52.50 not 51.50

answer: procent 54 wynosi 33,33%
