A science teacher ordered S2278 worth of microscopes and dissection kits for the new science lab. A total of 26 microscopes and 56 dissection kits were ordered. A microscope costs three times as much as a dissection
kit. Write a system of linear equations that represents this situation. What is the cost of each item?

---- equation 1

---- equation 2

A microscope costs S51 and a dissection kit costs S17

Step-by-step explanation:

Given

Represent microscope with M and Dissection kits with D

Cost:

Required

Represent as an equation:

To do this, we represent the equation in terms of cost and quantity

In terms of cost, we have:

---- equation 1

and

---- equation 2

Substitute 3D for M in equation 1

Divide both sides by 134

Substitute 17 for D in

Hence:

A microscope costs S51 and a dissection kit costs S17

1/800 is the right answer
