Miles is heading to the local department store with the following two coupons: 20% off Total Purchase and 10% off total purchase

Miles chooses a sweater to buy that has an original price of $19.99. If both coupons can be used to buy the sweater, which option below is true?

A. Using the $10 off coupon first, then the 20% off coupon produces the cheaper sale price.

B. Using the 20% of coupon first, then the $10 off coupon produces the cheaper sale price.

C. It doesn't matter which order the coupons are used because either order will produce the same sale price.

d

step-by-step explanation:

2 liters for 10   people

step-by-step explanation:

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
