Answer:

a=30 b=2 (not sure)

Step-by-step explanation:

Simplify first part : 2*3x+ 2*5= 6x+10+ax

Simplify 2nd part : 5*4x-5*b. 5x-5b

we have: 6x+10+ax=20x-5b.

we minus 6x from both sides

10+ax=14x+5b

Minus 10

ax=14x+5b-10

Divide x

a=14+5b-10

a=4+5b

divde 5

a/5= 4+b

perhaps it is 30

30/5=4+b

6=6

but i am not sure

nika2105 [10]

Answer:

The percent increase in the price of the car is <u>31.36%</u>.

Step-by-step explanation:

Given:

A car dealer buys a luxury car for $65,200 and sells it for $85,650.

Now, to find the percent increase in the price of the car.

Cost price of the luxury car = $65,200.

Sell price of the luxury car = $85,650.

So, the price of the car increased by:

Sell price of the luxury car - Cost price of the luxury car.

$=\$85,650-\$65,200\\\\=\$20,450.$

<em>Thus, the price of car increased by $20,450.</em>

Now,to get the percent increase in the price of the car:

$\frac{20450}{65200} \times 100$

$=0.3136\times 100$

$=31.36\%.$

Therefore, the percent increase in the price of the car is 31.36%.
