Step-by-step explanation:

Step 1: Define Equation

8(2x + 5) = 16x + 40

Step 2: Solve for x

Distribute 8: 16x + 40 = 16x + 40
Subtract 40 on both sides: 16x = 16x
Divide 16 on both sides: x = x

Here we see that x does indeed equal x.

∴ x has an infinite amount of solutions.

anygoal [31]

Answer:

37.5%

Step-by-step explanation:

This week, the cost is higher when we compare to last week. Therefore, the percentage difference is given by comparing the price differences to the price for the previous week.

Difference in costs=165-120=45

Percentage difference with respect to last week's price= $\frac {45}{120}\times 100=37.5%$

Therefore, percentage increase is 37.5%
