Answer:
For part A
10.08x=y
Step-by-step explanation:
252/25=10.08
x=number of hours=25
y=how much earned=252
10.08(25)=252
Step-by-step explanation:
As ratio of desktops to laptops=3:4
Take no. of desktops= 3x
Take no. of Laptops=4x
Total no. of desktops+ Total no. of laptops = Total no. of computers
3x+4x=70
7x=70
x=10
Hence, the total no, of desktops= 3x
Hence, Total no. of desktops= 3×10
=30 desktops
13/50
26/100, reduce it
2 can go into both 26 and 100 evenly
26/2 = 13
100/2= 50
It cant be reduced anymore

Answer:
- $10,000 at 5%
- $22,000 at 6%
Step-by-step explanation:
Let x represent the amount invested at 6%. Then 32000-x is the amount invested at 5%, and the total interest earned is ...
0.06x +0.05(32000 -x) = 1820
0.01x +1600 = 1820 . . . . simplify
0.01x = 220 . . . . . . . . . . subtract 1600
x = 22,000 . . . . . . . . . . . multiply by 100
32000 -x = 10,000
Phyllis invested $22,000 at 6% and $10,000 at 5%.
