Answer:
One large gift costs <u>$60.</u>
Step-by-step explanation:
Mary spent $200 (20 x $10) on small gifts. This means that:
Mary = $200 + 1 large gift
Melanie spent $20 (2 x $10) on small gifts. This mean that:
Melanie = $20 + 4 large gifts
Because the amount Melanie and Mary are equal, we know that:
<u>$200 + 1 large gift = $20 + 4 large gifts</u>
To work out the cost of 1 large gift, you first need to work out the difference of large gifts. (4-1=3). Melanie bought <u>3 more</u> large gifts than Mary.
This means that:
<u>$200 = $20 + 3 large gifts</u>
Then, subtract $20 from both sides.
<u>$180 = 3 large gifts</u>
Finally, divide both sides by 3 to find the cost of 1 large gift.
<u>$180 ÷ 3 = </u><u>$60</u>
