Answer:
Step-by-step explanation:
Last week, burton paid $36.80 for 11 1/2 gallons of gas. Converting 11 1/2 gallons of gas to decimal, it becomes 11.5. The rate at which Burton bought one gallon of gas last week would be
36.80/11.5 = $3.2
The cost per gallon of gas increased by 5% between last week and this week. The amount by which it increased would be
5/100 × 3.2 = 0.05 × 3.2 = $0.16
The cost of one gallon of gas for this week would be
3.2 + 0.16 = $3.36
She bought 9 1/4 gallons of gas this week. Converting 9 1/4 gallons of gas to decimal, it becomes 9.25 gallons of gas. The amount that she paid for gas this week would be
9.25 × 3.36 = $31.08
Answer:40 bushels of seed would be required to plant 30 acres of wheat.
Step-by-step explanation:
On the average, 1 1/3 bushels of seed are needed to plant 1 acre of wheat. Converting 1 1/3 bushels of seed to improper fraction, it becomes 4/3 bushels of seed.
Let x represent the bushels of seed that would be required to plant 30 acres. Therefore
4/3 bushels of seed = 1 acre
x = 30 acres
Cross multiplying
x × 1 = 4/3 × 30
x = 40 bushels of seed
