Answer:there are 16 goats and 22 chickens.
Step-by-step explanation:
Let x represent the number of goats in the field.
Let y represent the number if chicken in the field.
After a quick count, you determine there are 38 heads and 108 feet in the field. A goat has one head. A chicken also has one head. It means that
x + y = 38
A goat has four legs. A chicken has 2 legs. It means that
4x + 2y = 108 - - - - - - - - - - - 1
Substituting x = 38 - y into equation 1, it becomes
4(38 - y) + 2y = 108
152 - 4y + 2y = 108
- 4y + 2y = 108 - 152
- 2y = - 44
y = - 44/ - 2
y = 22
x = 38 - y = 38 - 22
x = 16
Answer:
$96.55
Step-by-step explanation:
The computation of the money he would require is shown below:
Since lee wants to buy both pairs of shoes and the two pairs of socks
So the amount of money he needed is
= $37.07 + $42.48 + 2 × $8.50
= $37.07 + $42.48 + $17
= $96.55
100% - 81% = 19%
19% did not pass.
