Answer:
m = $6.5
s = $3
Step-by-step explanation:
Raul ordered 1 small photo enlargement and 4 medium photo enlargements for $29. Patricia ordered 5 small photo enlargements and 2 medium photo enlargments for $28. determine the price of the small photo enlargements and medium photo enlargments
two equations can be derived from the question
s + 4m = 29 equation 1
5s + 2m = 28 equation 2
where
s = small photo enlargements
m = medium photo enlargements
multiply equation 1 by 5
5s + 20m = 145 equation 3
subtract equation 2 from 3
18m = 117
m = 6.5
substitute for m in equation 1
s = 29 - (4 x 6.5)
s = 3
Check the picture below.
now, we're assuming "to the building" means "to the ground", since we don't know the building's height, so we're also assuming the 1200m is above the building, as you see in the picture.
make sure your calculator is in Degree mode.
