13) Ryan works two jobs. He earns $10 per hour working at the hardware store, and he earns $13 per hour working at the shipping

company. If x represents hours at the hardware store and y represents hours at the shipping company, which inequality represents

the situation if Ryan wants to earn a minimum of $300?

A)

10x + 13y s 300

B)

10x + 13y = 300

13x + 10y s 300

D)

13x + 10y = 300

Given :

Ryan works two jobs. He earns $10 per hour working at the hardware store, and he earns $13 per hour working at the shipping.

To Find :

If x represents hours at the hardware store and y represents hours at the shipping company, which inequality represents  the situation if Ryan wants to earn a minimum of $300.

Solution :

His total earning is given by :

T = 10( number of hours at hardware store ) + 13( number of hours at the shipping)

T = 10x + 13y

Now, he wants to earn a minimum of $300 i.e T ≥ $300.

So, 10x + 13y ≥ 300

Hence, this is the required solution.

step-by-step explanation:

π^°×{{€€

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
