Question

Two friends, Aria and Kaylee, took summer jobs. The equation y = 20.2 x y=20.2x represents Kaylee's earnings in dollars and cents, y y, for working x x hours. Aria earned $737.20 in 38 hours.

Answer 1

Answer:

y=19.4x------represents Aria's earnings in dollars and cents,

Step-by-step explanation:

The question is not complete, however, the idea from this response can provide the needed solution and understanding

 Step one:

The linear function for the earnings is given as

y = 20.2x-----this represents Kaylee Earnings.

y represents the total earnings

x represents the earning rate, in this situation it $20.2 per hour, this is also the gradient of the function m

Step two:

we want to find th equation for Aria earning

y= $737.20

time taken x=38 hours

737.2=m(38)

divide both sides by 38

m=737.2/38

m=19.4

this means that Aria earn $19.4 per hour

the function for Aria is

y=19.4x
