Question

Can someone walk me through this!!!!

Alex is ordering salads and drinks for his friends. Salads cost $8 each, drinks cost $4 each, and there is a $6 delivery charge per order. He has $70. If he buys 4 salads, how many drinks can he buy?
Solve the inequality 8x + 4y + 6<=70, where x = number of salads and y = number of drinks, to answer the question.

Answer 1

so... say if we had instead " \(\bf 8x + 4y + 6=70 \) " what would it give you if you solve it for "y" ?

Answer 2

dont we need somethimg for x first?

Answer 3

8x+4y=64

Answer 4

8x + 4y + 6<=70
8x+4y+6=70
8x+4y=70-6
8x+4y=64
now we have given that x=4 number of salad and we need to find y=number of drinks so putt x=4 in last equation.
8(4)+4y=64
32+4y=64
4y=64-32
4y=32
y=32/4
y=8 is the number of drinks.
