The product of 8/9 and the sum of a number and – 4 is less than or equal to 64.

Fiesta28 [93]

Answer:

$x\leq 76$

Step-by-step explanation:

Let x = unknown number

$\implies \dfrac89 \times (x-4)\leq 64$

$\implies \dfrac{8(x-4)}{9}\leq 64$

Multiply both sides by 9:

$\implies 8(x-4)\leq 576$

Expand brackets:

$\implies 8x-32\leq 576$

Add 32 to both sides:

$\implies 8x\leq 608$

Divide both sides by 8:

$\implies x\leq 76$

To find how many people 60% is you need to do 0.60 × 220 = 132

Now you know that 60% of 220 is 132.

Then subtract 132 from 220

220 - 132 = 88

The answer is 88
