Create an expression to represent the following<br><br> (picture is included below)

zheka24 [161]

Answer:

7) x + 0.09x, where x is the price of the car

8) x + 0.05x where x is the price of clothing

9) It will take michael about 9.14 minutes to eat 32 cookies.

Step-by-step explanation:

7) 9% of x is the same as 0.09x, so you can write this:

x + 0.09x, where x is the price of the car

8) same thing for this one

x + 0.05x where x is the price of clothing

9) michael can eat cookies at a rate of 21 cookies per 6 minutes, or $\frac{21}{6}$

Because he will be eating them at the same pace, you can write an equation and solve for the variable:

$\frac{21}{6}$ = $\frac{32}{y}$

cross multiply the proportion:

21 × y = 32 × 6

solve:

21y = 192

y ≈ 9.14

It will take michael about 9.14 minutes to eat 32 cookies.

This works because they both simplify to 3.5 cookies per minute

$\frac{21}{6}$ = 3.5

$\frac{32}{9.14}$ = 3.5
