Answer:
There area 14 one cent stamps
Step-by-step explanation:
Let
x -----> the number of 1 cent stamps
y -----> the number of 8 cent stamps
z -----> the number of 12 cent stamps
we know that
0.01x+0.08y+0.12z=1.78 -------> equation A
x=y+4 ------> y=x-4 -----> equation B
x=2z -----> z=0.5x ------> equation C
substitute equation B and equation C in equation A and solve for x
0.01x+0.08(x-4)+0.12(0.5x)=1.78
0.01x+0.08x-0.32+0.06x=1.78
0.15x=1.78 +0.32
0.15x=2.10
x=14
therefore
There area 14 one cent stamps
1)
8.75 * 20 = 175
8 * 20 = 160
175 - 160 = 15
He'd make $15 more working at the amusement park.
2)
Semi-monthly means twice a month. So, her company is going from 2 to 4 pay periods.
3280 * 2 = 6560 (is what she makes per month)
6560/4 (because 4 weeks in a month) = 1640
OR (An alternative method.)
3280/2 = 1640
She'll be paid $1640 per week.
4)
105,000/12 (12 months in 1 year) = 8750 (He makes this per month)
8750 * 2 = 17500
He makes 17500 semi monthly
8750 /4 = 2187.5
2187.5 * 2 (because bi-weekly) = 4375
He makes 4375 bi-weekly
8750/4 = 2187.5
He makes 2187.5 every week
Dont forget to add the dollar signs. I didnt add them, but you need to. If you need me to add them I can.
