Answer:
x = 4y + 5
Step-by-step explanation:
x represents the total students in the class. We don't know how many teams of four there will be, so we represent that with y. 4y represents the total students in teams of 4. We know there is one team of 5, so that is added to 4y.
using order of operations (PEMDAS) your answer should be 46
you do multiplication before addition.
The minimum cost option can be obtained simply by multiplying the number of ordered printers by the cost of one printer and adding the costs of both types of printers. Considering the options:
69 x 237 + 51 x 122 = 22,575
40 x 237 + 80 x 122 = 19,240
51 x 237 + 69 x 122 = 20,505
80 x 237 + 40 x 122 = 23,840
Therefore, the lowest cost option is to buy 40 of printer A and 80 of printer B
The equation, x + 2y ≤ 1600 is satisfied only by options:
x = 400; y = 600
x = 1600
Substituting these into the profit equation:
14(400) + 22(600) - 900 = 17,900
14(1600) + 22(0) - 900 = 21,500
Therefore, the option (1,600 , 0) will produce greatest profit.

Out of 320 student, you should expect about 25% of them to score above 284, or about 80 students.
Answer:
SP is Rs 800.
Step-by-step explanation:
MP = Rs 875
Discount = Rs 75
so
SP = MP - discount
= Rs 875 - Rs 75
= Rs 800
