Jesse has to save 60% of the total cost to go to a sports camp during the summer. The total cost was $500. What was the total amount Jesse saved? Make sure to explain how you got it.

$300

Step-by-step explanation:

The total cost is $500 so you must find 60% of that. To find percentage divide 60% by 100 which turns it into .60, and then you multiply .60 by 500. This equals to 300. So, Jesse 60% of 500 is 300, and so Jesse had to save $300

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
