Question

PLS HELP !!

Answer 1

For this case we have that the weight of the bouquet of flowers will be:
 4.3 * 10 ^ 4 - 2 * (7.5 * 10 ^ 2)
 Rewriting we have:
 4.1 * 10 ^ 4 miligrams
 Thus, we have that the values of p and q are given by:
 p = 4.1
 q = 4
 Answer:
 4.1 * 10 ^ 4 miligrams
 p = 4.1
 q = 4

Answer 2

p = 4.1

q = 4

because anything else would just be irrelevant
