P stands for pineapple, p for pear, m for mango, and a for apple. Given a = 4*m, p = 2*a, and P = m; if they utilized 8 pineapples in their latest batch, they used 32 apples (calculated as 4*8) and 64 pears (calculated as 2*32).
Response: the equations are
0.02x + 0.07y = 156
y = 300 + x
Step-by-step explanation:
Let x denote the dollar amount from phone sales made by Josiah.
Let y indicate the dollar amount from his computer sales.
Josiah receives a 2% commission on his phone sales total and 7% on his computer sales. He accumulated a total of $156 in commission, leading to the equation
0.02x + 0.07y = 156 - - - - - - - - - - -1
Furthermore, it’s given that Josiah had $300 more in computer sales than in phone sales, expressed as
y = 300 + x
