Find the unit price if 7 pounds of sugar sells for $2.50

36 cents

Step-by-step explanation: Unit price means the cost per unit which in this case is the cost per pound of sugar.

Since we know that it costs $2.50 for 7 pounds of sugar, to find the cost for 1 pound of sugar, we need to divide 7 into $2.50 or just 2.50 ÷ 7.

2.50 ÷ 7 = 0.357142857 which we can round up to 36 cents.

Therefore, the unit price is 36 cents per pound of sugar.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
