Question

A phone sells for $700. It is now on sale for 1/5 off the
original price. Megan has a coupon for an extra 10% off the
sales price. To the nearest dollar, how much less than the
original price will Megan pay for the phone? (what is the
total discount) *​

Answer 1

$\text{Find how much she was discounted:}\\\\\text{We know that the base price of the phone is 700}\\\\\text{It's on sale for 1/5 of the price (20\%), so multiply 700 by 0.20 and subtract}\\\\700*0.20=140\\\\700-140=560\\\\\text{Now, we know that there's a 10\% discount off the sale price, so precede}\\\text{with the same steps}\\\\560*0.10=56\\\\560-56=504\\\\\text{To find total discount price, subtract 504 from the original price}\\\\700-504=196\\\\\boxed{\ 196}$
