Answer:
c) 3.5%
Step-by-step explanation:
First, determine the difference between their old and new salary:
$44,505 – $43,000 = $1,505
Next, divide the raise amount by the old salary:
$1,505 / $43,000 = . 035
To turn the decimal into a percentage, multiply by 100
0.35x100=3.5%
Answer:
B
Step-by-step explanation:
essentially the plan that increases the price the most per week reaches the goal of $12 fastest.
plan A is $0.10 per week.
plan B it is not clear, if it means 10% of the original price every week, or every week 10% of the price of the previous week. I assume the first and simplest.
that means 10% of $8 = $0.80 per week.
plan C : the same amount every week until reaching $12. we need to increase in total by $4 (from $8 to $12). to reach these $4 in 8 weeks, we need to increase the price every week by 4/8 = $0.50.
plan D : $0.25 per week.
so, the plan with the highest increase every week and therefore the fastest one reaching $12 is plan B.
20*39 = 780
780+100 = 880
880-314.23-123 = 442.77
442.77/3
