Answer:

Answer is 28/4 = 7

Step-by-step explanation:

Given

Beth B = 28 problem

B has 4 times more problem than Mery m

Find

Total number of problem Mery m has if Beth has 4 times more problem than Beth

So,

B = 4 x m

m = B/4 = 28/4 = 7

Finally answer (d) is correct which is 28 ÷ 4 = m

The salary at Beth’s company is $32,000 for someone with no experience and increases by $2700 per year of experience. Write a ru
AlekseyPX

Answer:

In general, the salary S in terms of years of experience Y is S = 2700Y + 3200

Step-by-step explanation:

we start at 32000 without experience.

as the experience goes up, the wage increases 2700 per year so we can multiply 2700 by the years of experience to find the increase of salary. To find the salary of a certain employee with a certain amount of experience, plug the years of experience in for Y and solve.

for Y=0

S= 2700(0) + 3200 = 0 + 3200 = 0

for Y=2

S= 2700(2) + 3200 = 5400 + 3200 = 8600

for Y=5

S= 2700(5) + 3200 = 13500 + 3200 = 16700

for Y=7

S=2700(7) + 3200 = 2700(5) + 2700(2) + 3200 = 5400 + 13500 + 3200 = 22100
