The sports boosters club is having a bake sale to buy uniforms. they want to raise $250. they need to rent a booth for $20. how many dozen cookies will they need to sell if they charge $3 per dozen?

which equation could be used to solve this problem?

1. 250 = 3c - 20

2. 250 = 3 - 20c

3. 250 = 20 - 3c

4. 250 = 20c - 3

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
