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

Divide through by 2



Answer:

Step-by-step explanation:
Let p be the number of identical packages.
We have been given that each package has a mass of 37.4 kg, so weight of p packages will be 37.4p.
The total mass of Renna and her load of identical packages is 620 kg.
We have been given that the mass limit for the elevator is 450 kg. This means that Renna can remove p packages from 620 kg such that 620 minus weight of p packages will be less than or equal to 450 kg.
We can represent this information in an inequality as:

Therefore, the inequality
can be used to determine the number of packages, p, Renna could remove from the elevator to meet the mass requirement.
