Answer: 2, 3, 6, 8 (top) 1.40, 2.10 4.20, 5.60 (bottom)
Step-by-step explanation: If 1 pound = 0.70, then 2*0.70=1.40. 2.10 divided by 0.70=3. 0.70*6=4.20. 0.70*8=5.60.
Alexandra's gross annual salary is $38,556. The maximum amount of rent she can afford to pay can be determined by first solving for her monthly gross salary.
Monthly Salary = ($38,556/ 12 months) = $3,213
Assuming that the amount allocated for her rent is 30% of her monthly salary, the maximum amount of rent that she can afford to pay is:
Max allowable rent = $3,213 * 0.30 = $963.90<span />

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
