Answer:
a) $1056.33 b) 23 years
Step-by-step explanation:
a) 10000(1+1.85/100)^3=10565.33 (2d.p.)
b) let x be the no. of years
15000 = 10000(1+1.85/100)^x
1.5 = 1.0185^x
ln both sides
ln 1.5 = x ln 1.0185
x = ln 1.5/ln 1.0185
=22.11
=23 years (rounded up)
Answer:
0.1 yards of fabric
Step-by-step explanation:
Data provided in the question:
Number of outfits made for the doll = 14
Fabric used in each outfit = 
yards of fabric
Starting fabric available = 10 × 
or 
yards
Now,
The total fabric used in making the outfits of 14 dolls
= 14 × yards of fabric
= 
yards of fabric
Therefore,
The fabric left after making the outfits
= Fabric available in the start - Fabric used in making the outfits
= yards - yards
= 
yards
= 
yards
= 
yards
= 0.1 yards of fabric
Answer: The manager should sell the chair for $1740.
Step-by-step explanation:
45% of 1200 Solve this to find the amount increase
0.45 * 1200 = 540 Now add this amount to find the price.
$1200 + $540 = $1740
or you could do it this way
100% + 45% = 145%
145% of 1200 =?
1.45 * 1200 = 1740
Answer:
7 are boys
Step-by-step explanation:
Make a system of equations where g is for girls and b is for boys.
b+g=26
g=3b-2
Substitute "3b-2" in for "g" in the first equation.
b+(3b-2)=26
Rewrite without the parentheses because it's addition and not multiplication.
b+3b-2=26
Combine like terms.
4b-2=26
Add 2 to both sides.
4b=28
Divide by the coefficient of the variable to get it alone.
b=7
