Watermelons are on sale for $3 each, but customers can buy no more than 4 at this price.
For watermelons bought at the sale price, the total cost, y, is directly proportional to the number bought, X .This function can be modeled by y=3x.
What is the domain of the function in this situation?
OA. Al positive numbers, x >0
OB. (0, 3, 6, 9, 12}
Oc. (0, 1, 2,3, )
O D. 0, 1, 2, 3, 4}

46.2+112.3

step-by-step explanation:

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
