Answer:
Cost of a kit is $20
cost of a microscope is $80
Step-by-step explanation:
Here, we want to write a set of equations and solve
Let the cost of a microscope be $m while the cost of a kit be $k
Total cost of 38 microscopes will be 38 * m = $38m
Total cost of 47 kits = 47 * k = $47k
The sum of these is $3980
That will be;
47k + 38m = 3980 ••••••(i)
A microscope cost 4 times a kit
Mathematically;
m = 4k •••••••••(ii)
Substitute ii into i
47k + 38(4k) = 3980
47k + 152k = 3980
199k = 3980
k = 3980/199
k = $20
Recall;
m = 4k
m = 4 * 20 = $80
Answer:
$30
Step-by-step explanation:
cost of tip is represented by 25 multiplied by 0.2:
25*0.2=5
add onto original price:
25+5=30
good luck :)
Answer:
$8.33 per hour
Step-by-step explanation:
4(8.25) = $33 earned at the sporting goods store
2(10) = $20 earned shoveling snow
$53 = total earned in 6 hr.
53/6 = $8.33 per hour to nearest penny
$53/6 = exact amount earned per hour
