Monica has $20. She needs to buy a gallon of milk that costs $2. 50. She also wants to buy yogurt, which costs $1. 20 a cup. Which inequality can you use to find the number of cups of yogurt Monica can buy? 1. 20x 2. 5 Greater-than-or-equal-to 20 1. 20x 2. 5 Less-than-or-equal-to 20 1. 20x 2. 5 < 20 1. 20x 2. 5 > 20.

Explanation:

x = number of cups of yogurt

1.20x = cost of all the yogurt only

1.20x+2.50 = adding on the cost of milk

We set this expression to be less than or equal to 20.

In other words, the highest 1.20x+2.50 can go is 20 since $20 is her budget.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
