Answer:

in about 27 days

Answer:

3.86 weeks/three weeks

Step-by-step explanation:

x time it takes for thier vocab to be the same in days

so the boy lerns 360 words of spanish in a year

or 360/365 words of spanish per day which is 72/73 words per day

so,

100+4x=180+72x/73

80=288x/73-72x/73

80=216x/73

80*73=5,840

5,840=216x

27.037 days=x

so now we have to divide by seven to get weeks so that is 3.86 weeks.

so some time in week three

Alchen [17]

Amount of money Aisha receive from selling all of the bracelets is $33.25.

<u>Step-by-step explanation:</u>

In this question, its given that Aisha made bracelets for a craft fair. She spent $29.75 on supplies to make the bracelets. Each bracelet cost her about $0.85 to make. Aisha sells each bracelet for $0.10 more than it cost her to make. Let's calculate Number of bracelets Aisha made as \frac{total-cost}{cost-of-one-bracelet}.

Number  = \frac{total-cost}{cost-of-one-bracelet}

⇒ Number  = \frac{total-cost}{cost-of-one-bracelet}

⇒ Number  = \frac{29.75}{0.85}

⇒ Number  = 35

Now , its given that Aisha sell these bracelets with $0.10 more then it cost her i.e. at $0.95 , Let's calculate selling price as :

Price = 0.95(35)

Price = $33.25

Therefore, amount of money Aisha receive from selling all of the bracelets is $33.25.
