Answer:

The system of equation is $\left \{ {{d=15} \atop {d=0.5m}} \right.$ .

After 30 miles all the sponsors donate the same amount.

Step-by-step explanation:

Given:

Amount of donated by each of the other sponsors = $15

Amount donating by one person per mile = $0.5

We need to write the system of equation to model the donation d for m miles biked.

Also We need to find the number of miles all sponsors donate the same amount.

Solution:

Let the amount donated be denoted by 'd'.

Let number of miles biked be denoted by 'm'.

Now we know that;

Amount of donated by each of the other sponsors = $15

so we can say that;

$d=15$

Also We know that;

Amount donating by one person per mile = $0.5

So we can say that;

$d=0.5m$

Hence The system of equation is $\left \{ {{d=15} \atop {d=0.5m}} \right.$ .

Now to find the number of miles when all the sponsors donate the same amount we will make both the equation equal we get;

$0.5m=15$

Dividing both side by 0.5 we get;

$\frac{0.5m}{0.5}=\frac{15}{0.5}\\\\m=30\ miles$

Hence After 30 miles all the sponsors donate the same amount.

George went to the supermarket and he bought bananas for his monkeys. They were $5.99. He got a family discount because his wife

BlackZzzverrR [31]

Answer:

$4.49

Step-by-step explanation:

If bananas are $5.99, we need to find 75% of the price, or 25% off. There are two ways we can do this, I'll show the more detailed way. First, we multiply 5.99 by .25 to find 25% of it. We got ~1.50. This means that 25% of 5.99 is 1.50. Now, we take away 1.50 from 5.99. This gets us $4.49. That means the price of the bananas with the discount is $4.49. The other way we can do this is multiply 5.99 and .75 (because 25+75=100). This gets us 4.4925, which rounds to $4.49. I hope this helps!
