Answer:
35 bricks for $25.90
35 bricks for $25.90
230 bricks for $170.2
Step-by-step explanation:
Cost per brick = number of bricks / price of bricks
1500/$1110 = $1.35
1300 / $845 = $1.54
230 / $170.20 = $1.35
100 / $75 = $1.33
35 / $25.90 = $1.35
Based on these calculations, the bricks that have the same cost per brick are :
35 bricks for $25.90
35 bricks for $25.90
230 bricks for $170.20

Step-by-step explanation:
Answer:
$720
Step-by-step explanation:
$20000 - 100%
$x. - 2.5%
x=(20000*2.5)/100=500
20000+500=$20500 in one year (Mark)
20000 - 100
x. - 6.1
x= (20000*6.1)/100 = 1220
20000+1220= $21220 (Walter)
21220-20500= $720 more (Walter will have after 1 year)
