8.0% is the answer. To solve these problems just do actual length minus her guess which gives you 0.5. Then divide what you got by the actual length. 0.5 divided by 6.25 is 0.08. Multiply that by 100. 0.08 x 100 is 8 which means the answer is 8.0% :)
Let, the number of weeks = x
It would be: 17 + 11x ≥ 72
Subtract 17 from both sides,
11x ≥ 55
Divide by 11,
x ≥ 5
So, at-least he needs 5 weeks for that

Answer:
x = -8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(3x−2)=8(2x+3)
(4)(3x)+(4)(−2)=(8)(2x)+(8)(3)(Distribute)
12x+−8=16x+24
12x−8=16x+24
Step 2: Subtract 16x from both sides.
12x−8−16x=16x+24−16x
−4x−8=24
Step 3: Add 8 to both sides.
−4x−8+8=24+8
−4x=32
Step 4: Divide both sides by -4.
−4x
−4
=

x=−8
Answer:
x=−8
30% = 0.30
0.30 × $75 = $22.50
Susan should put $22.50 in the bank to reach her goal.
