Step-by-step explanation:

Your question isn't complete and I couldn't get the exact question online but let's reframe it and solve it.

The restaurant manager wants to find how much they are spending for pies and cakes. Last week they payed 204$ for 12 pies and 8 cakes. This week, they paid $129 for 5 pies and 7 cakes.

Let's say the cost of pies is x

Let's say the cost of cake is y.

We'll then use the information given to make an equation which will be:

Last week they payed 204$ for 12 pies and 8 cakes. This will be:

12x + 8y = 204 i

This week, they paid $129 or 5 pies and 7 cakes. This will be:

5x + 7y = 129 ii

Therefore,

12x + 8y = 204 i

5x + 7y = 129 ii

Multiply equation i by 5

Multiply equation ii by 12

60x + 40y = 1020 iii

60x + 84y = 1548 iv

Subtract iii from iv.

44y = 528

y = 528/44

y = 12

The cost of cake is $12.

From equation i,

12x + 8y = 204

12x + 8(12) = 204

12x + 96 = 204

12x = 204 - 96

12x = 108

x = 108/12

x = 9

The cost of pies is $9.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
