On Monday Harold picked up four donuts and two large coffees for the office staff. He paid $4.74. On Tuesday Melinda picked up two donuts and five large coffees for the office staff. She paid $5.93. What is the cost of one donut? What is the cost of one large coffee?

Answer 1

4d+2c = 474
2d+5c = 593
now solve as usual

Answer 2

How do I solve that please explain further

Answer 3

for example
4d+2c = 474
2d+5c = 593 multiply this equation by 2

4d+2c = 474
4d+10c = 1186
---------------------- subtract
0 d - 8 c = - 712
c = 89
now go back and find d from either of the two original equations
