A company charges $60 per day plus $0.50 per mile for truck rentals. If Greg rents a
truck for 3 days and drives it a total of 150
miles, what will the company charge?

$225

Step-by-step explanation:

$60 ×3=$180

150 ×$0.50 = $75

$180+ $75= $225

the company will charge $225

y = 44

Step-by-step explanation:

Well if y varies directly with x it means that when y increases x increase and if y decrease x also decreases.

So let us put this in a equation,

y = kx

where 'k' is constant

so k = y/x

let us put the figures of x and y from given first statement;

x = 7 and y = 18

so, k = 18 / 7

which means, k = 2.57

lets put this value of k in the equation above,

we know from statement that, x = 17 and k = 2.57

so, y = 2.57 (17)

which means, y = 43.71

or we can round it off to, y = 44
