Answer:
New cost of jacket = 
New costs of skirt = 
Step-by-step explanation:
Let original cost of jacket = 
original cost of skirt = 
The equation will be

New cost of jacket = 
New costs of skirt = 
The equation will be

The equations are




Subtracting the above two equations we get


New cost of jacket = 
New costs of skirt =
.
There are two ways you can do this. You can use the longer way:
15+16+17+18+19+20+21+22+23+24 = 195 (starting from the top row, which has 15 logs, up until the bottom row, which has 24 logs, on condition that each second row has one log more than the previous one)
You can also use the formula (where n is the number of rows)
x= (n(first term+last term))/2
x= (10(15+24))/2
x= (10*39)/2
x=390/2
x=195
Either way, there are 195 logs in the stack.
50 meters, because if 4cm is 5 m, then it would be 5( 4cm, which equals 5m) multiplied by 10( 8cm÷4cm= 2. 2×5m= 10). So 5m × 10m = 50m. Hope this helps!
