mr. sanchez’s class sold fruit pies for $1.65 each and mr. kelly’s class sold bottles of fruit juice for $1.36 each. together, the classes sold 79 items and earned $118.17 for their school.
(a) write and solve a system of equations that model the problem. show all your work.
(b) which class earned more money?
(c) how much more money did that class earn?

(c) $3,93 more

(b) Mr. Sánchez's class earned more money.

(a)

Step-by-step explanation:

{79 = p + j

{118,17 = 1,65p + 1,36j

−25⁄34[118,17 = 1,65p + 1,36j]

{79 = p + j

{−86 121⁄136 = −1 29⁄136p - j >> New Equation

__________________________

[Plug this back into both equations above to get the j-value of 42];

The next step is to plug the solution into the BOTTOM EQUATION to calculate the total money earned for each class:

Sánchez's class

Altogether, thirty-seven fruit pies cost $61,05.

Kelly's class

Altogether, forty-two bottles of fruit juice cost $57,12.

* Based on the calculation, it is perfectly clear that Mr. Sánchez's class earned more money by $3,93:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
