Answer:

x = 6 y = 5

Step-by-step explanation:

-8x + 3y = -33

y = -5x +35

-8x + 3(-5x + 35) = -33

-8x - 15x + 105 = -33

-23x + 105 = -33

-23x = -138

x = 6

-8(6) + 3y = -33

-48 + 3y = -33

3y = 15

y = 5

Yvonne is a salesperson who earns a fixed amount of $1,850 per month. She also earns a commission of 4% on the amount of goods t

stellarik [79]

Let the amount of dollars in goods sold be x, then her earning is 1850 + (4/100)x = 1850 + 0.04x.
For her to earn more than $2300, we have:
1850 + 0.04x > 2300
0.04x > 2300 - 1850
0.04x > 450
x > 450 / 0.04
x > $11,250

Mr. saslow has $32 for the class party. he spends $17 on the drinks and the cake. which of the inequalities represents the money

harkovskaia [24]

Answer:

I don't see any options for inequalities, so I wrote one based on the information.

Step-by-step explanation:

We'll assume that the drinks and cake ($17) are the only items Mr. Saslow needs to purchase and that the remainder may be used on whatever extras he wants. In this case, candy.

He starts with $32 and spends $17. The remainder may be spent on candy (all or none). This can be expressed as an inequality. Let C be the cost of the candy.

C $\leq$ ($32 - $17)

C $\leq$ ($15)
