Hello!

to solve this, do the following equation:
x=brand x copier
y=old version

x=y+(y*.1)  or  x=y*1.1

using either of these equations, the math I will show will get you the correct answer

462=420+(420*.1)  or  462=420*1.1

your final answer is:  the new copier produces 462 copies per hour

I hope this helps, and have a nice day!

In Bobby’s school, math grades for the year are calculated from assignments, tests and a final exam. Assignments count 30%, test
jarptica [38.1K]

Answer:

A) Bobby's overall grade is 70.4%

Step-by-step explanation:

To solve this problem we must calculate the percentages each grade represents from the overall grade. Therefore:

assignment = 85*30% = 85*30/100 = 25.5%

tests = 72*20% = 72*20/100 = 14.4%

exam = 61*50% = 61*50/100 = 30.5%

total = assignment + tests  + exam

total = 25.5 + 14.4 + 30.5 = 70.4

Bobby's overall grade is 70.4%. Therefore the correct answer is A).
